Infrared Analyzer

2009-02-08T04:17:00.000-08:00

INFRARED ANALYZER

The above diagram provides a graphic representation of the basic design of an infrared analyzer which is used to measure breath alcohol concentrations. The design is based on the fact that specific wavelengths of infrared energy are absorbed by ethyl alcohol molecules. In its simplest form, the instrument's detector measures the change in the amount of a specific wavelength of infrared energy that passes from the infrared source (lamp), through the sample chamber and filter wheel to the detector. The change in response on the detector, as a breath sample is submitted to the sample chamber , is monitored and analyzed by a processor in the instrument. The change in the signal is used to calculate an alcohol concentration

The difference between the amount of infrared energy that reaches the detector when the sample chamber is free of compounds that absorb the infrared energy and the amount of infrared energy that reaches the detector when a subject's breath sample is within the sample chamber, provides an indication of the concentration of the absorbing substances in the sample . If ethanol was the only molecule found in a breath sample that would absorb energy at the wavelength being recorded by the detector, the calculated difference in infrared energy reaching the detector could be used by itself to establish the concentration of alcohol in the breath sample. Unfortunately this is not always the case.

In order to deal with the lack of specificity, it is important that the primary wavelength of infrared energy used to measure the concentration of alcohol is selected based upon its limited cross sensitivity to other substances that are commonly found in the human breath. The spinning filter wheel in the diagram above is used to modulate the light through several different filters allowing different wavelengths of infrared energy to be transmitted to the detector for analysis. The secondary wavelengths of energy are selected based upon the interfering compounds that could be found in a human breath sample. If these compounds are identified and are in concentrations that would adversely effect the calculated ethanol result, the analysis can be aborted.

One other important point is that the differing concentrations of alcohol or other energy absorbing compounds found in the subject's breath sample are not in a one to one relationship with the amount of energy that reaches the detector. In other words, a .050 alcohol concentration may absorb X units of infrared energy, but a .200 will not absorb 4X units of infrared energy. This inherent non-linearity can be overcome by performing a multi-point calibration. To ensure that the instrument is properly quantifying alcohol and the other substances, it would be prudent to perform multi-point accuracy checks for each substance of interest and ensure proper calibration over the entire range of substances and concentrations.

Finally, infrared systems require power to light the IR source, heat the sample chamber, power the light modulator and drive the detector and associated circuits. Historically, the signal from the detector has been small relative to the noise generated in the system. This has made it difficult to resolve changes in the signal when low level concentrations of alcohol are presented to the system. To solve this problem, several manufacturers have included cooled detectors. These systems require additional power, but the cooled detector decreases the noise on the detector and enhances the instrument's performance at the low alcohol

NIR Tech Oxygen Analyzer

2009-02-08T04:16:00.000-08:00

Today’s oxygen analyzers use one of a several types of oxygen sensors. As industrial process applications call for improved measurement accuracy and repeatability, users are also demanding analyzers that require a minimum of maintenance and calibration. To this end, users of oxygen analyzers are encouraged to evaluate the merits of a particular oxygen sensor type in context to the application for which it is intended. There is no one universal oxygen sensor type.

The synoptic review of the various gas phase oxygen sensors provided below should be used in conjunction with information gathered from manufacturers of oxygen analyzers. This combination will help to ensure the selection of the right sensor type for the application under consideration.

Selecting a protocol analyzer

2009-02-08T04:11:00.000-08:00

Consultants have used a protocol analyzer or "sniffer" to help identify the source of problems on our network. I have been thinking about adding a tool like this to our collection but wasn't sure which one to use?
-- via the Internet

Choosing a protocol analyzer is not something that you should jump right into. There are several good candidates out there. The three most popular ones that I know of are Sniffer from Sniffer Technologies (www.sniffer.com aka Network Associates), Etherpeek from www.wildpackets.com and Ethereal from www.ethereal.com. I used to recommend a fourth candidate from Novell but they seem to have stopped supporting their software based analyzer. I haven't seen any new protocol decodes released for several years.

The cost of these ranges from free (in the case of Ethereal) to more than $10,000 for a fully equipped Sniffer package from Network Associates. I encourage you to get an eval copy of the above mentioned sniffers and run them through their paces. Etherpeek and Ethereal can be downloaded while Sniffer will require you to fill out a form and someone will call you in a couple of days to follow up.

NIR Paramagnetic Oxygen Sensors

2009-02-08T04:09:00.000-08:00

Within this category, the magnetodynamic or `dumbbell' type of design is the predominate sensor type. Oxygen has a relatively high magnetic susceptibility as compared to other gases such as nitrogen, helium, argon, etc. and displays a paramagnetic behavior. The paramagnetic oxygen sensor consists of a cylindrical shaped container inside of which is placed a small glass dumbbell. The dumbbell is filled with an inert gas such as nitrogen and suspended on a taut platinum wire within a non-uniform magnetic field. The dumbbell is designed to move freely as it is suspended from the wire. When a sample gas containing oxygen is processed through the sensor, the oxygen molecules are attracted to the stronger of the two magnetic fields. This causes a displacement of the dumbbell which results in the dumbbell rotating. A precision optical system consisting of a light source, photodiode, and amplifier circuit is used to measure the degree of rotation of the dumbbell. In some paramagnetic oxygen sensor designs, an opposing current is applied to restore the dumbbell to its normal position. The current required to maintain the dumbbell in it normal state is directly proportional to the partial pressure of oxygen and is represented electronically in percent oxygen. There are design variations associated with the various manufacturers of magnetodynamic paramagnetic oxygen sensors. Also, other types of sensors have been developed that use the susceptibility of oxygen to a magnetic field which include the thermomagnetic or `magnetic wind' type and the magnetopneumatic sensor. In general, paramagnetic oxygen sensors offer very good response time characteristics and use no consumable parts, making sensor life, under normal conditions, quite good. It also offers excellent precision over a range of 1% to 100% oxygen. The magnetodynamic sensor is quite delicate and is sensitive to vibration and/or position. Due to the loss in measurement sensitivity, in general, the paramagnetic oxygen sensor is not recommended for trace oxygen measurements. Other gases that exhibit a magnetic susceptibility can produce sizeable measurement errors. Manufactures of paramagnetic oxygen sensors and analyzers should provide details on these interfering gases.

Tytronic Sentinel Amine Analyzer

2009-02-08T04:06:00.000-08:00

APPLICATION

The Tytronics Sentinel Amine Analyzer is an online process analyzer that is capable of measuring acid gas loading in both rich and lean amines. It can be used to measure H2S content in amines (as sulphide), total acid gas loading (both CO2 and H2S), as well as amine strength. Multiple analyzers may be required depending on the number of analyte measurements, concentration range and distance between sampling points.

PRINCIPLE OF OPERATION

The Sentinel analyzer is a potentiometric titrator which uses an electrode to monitor changes in ion activity in the solution during the addition of a titrant, referred to as titration. An equivalence point or endpoint is reached when the ions in solution have completely reacted or complexed with the ions supplied through the titrant addition (there is no further ion activity). At the equivalence point the concentration and volume of the titrant solution added to the reaction cell determines the equivalent concentration corresponding to the analyte of interest.

It is this titration technique that is used to determine three main analytes of interest in the amine samples. These are as follows:

Amine Strength Determination - To know the exact loading of the amine, it is necessary to know the amine strength, a measure of the percentage by weight of an amine solution that is amine. This measurement is carried out using a color titration of lean amine.

Total Acid Gas Loading - The acid gas loading is determined by titration of the lean or loaded amine with a base, with the endpoint determined using pH measurement.

H2S loading - H2S loading is determined by potentiometric titration of the lean or loaded amine using a sulphide selective ISE.

FEATURES AND BENEFITS

If one of each amine analyzer variant is installed, the analog outputs from each unit can be combined in a data collection system to get a complete set of measurements for each stream - amine strength, H2S concentration, and CO2 concentration.

Regenerate amine only when necessary based on loading, reducing energy costs for regeneration and extending amine life.

Calibration based on lab results - monthly laboratory measurements of the parameters of interest are used to calibrate the analyzer

Reduced regenerator steam consumption by operating with residual H2S that ensures specification sweet gas instead of over-stripping to provide a safety margin

Reduced amine loss through carry-over

Reduced plant corrosion
