Why Smart Capillaries are the Smartest Choice in a Gas Divider
Because capillaries are static and probably will not change their performances for years and are ready to provide the best results as soon as the gas pressure is applied. Because capillaries are not always a stupid element : joined to PID electronic pressures control and using advanced setpoint calculations, applied physics give the base for relationships where all the influencing elements are ...

An easy way to test the dilution accuracy of the Gas Divider BETACAP60-3G
Introduction The testing procedure we want to present is not conventional because it’s not traceable : after having read this presentation, everybody is free to get his own evaluation about the utility or less of this testing procedure, whose efficiency is moreover confirmed by the results. The purpose of this test is to evaluate how much the capillaries installed in BetaCAP60-3G are ...

Diluting with Equal Capillaries Technique : why the best results ?
Equal pressures applied to equal capillaries induce equal flows. When equal flows are some from a gas to be diluted and some (the remaining) from a diluting gas, dilution is given by the ratio of integer numbers : the number of capillaries crossed by the gas to be diluted divided by the total capillaries number. The key for having very low uncertainty in dilution with a "Equal capillaries" gas ...

Gas Dilution With the Equal Capillaries Technique
The advantages of the equal capillaries technique are surprising and leads to reach accuracy values of one order of magnitude better than all the other dynamic dilution techniques. This comparison will be supported by analyzing the accuracy available with two different techniques. Nozzles (sonic or non-sonic) technique With this technique, a series of different size nozzles is used to provide, ...

Ease of Calibration & Maintenance
Conventional PIDs may use humidity suppression/compensation techniques but each of them has disadvantages: Humidity sensor – these typically have a slower response than the PID sensor itself which causes a drifting compensation Desiccant tube – these both slow the PID response and also reduce it by adsorption plus they need replacing from time to time which adds cost Humidify the ...

Calibration and Spectrum Troubleshooting: Span Calibration (Series Part 3 of 4)
In the previous blog, we learned about the general process for zero calibrations for AirSentry® II analyzers. In this entry, we learn how the next step after installation, span calibrations, empirically determine the influence that local atmospheric pressure has on AMC detection. Before you begin, the reactant peak (charged dopant) and target peak (charged AMC) should be identified in the ...

Preparation, Adoption, and Submittal of State Implementation Plans; Test Method 205, Appendix M
The purpose of this rule is to add a test method which would be used to verify the performance and accuracy of gas dilution systems during a field test. The test method is entitled, 'Verification of Gas Dilution Systems for Field Instrument Calibrations,' and will be added to 40 CFR part 51, appendix M, as Test Method 205. This method will allow the facility greater flexibility while assuring the ...

How Often Should Gas Detectors be Calibrated and by Whom?
Calibration frequency is one of the most commonly asked questions concerning the use of gas detection instruments. Common factors to consider when deciding how frequently to calibrate are: type of sensor, type of gas detector (fixed vs. portable), the required use and accuracy of the detector, manufacturer’s recommendations, how confident you are about the functioning of your instrument ...

ION Science PID Response Factors
PID Response Photoionization Detectors (PIDs) respond to a broad range of organic and a few inorganic gaseous and volatile chemicals (‘volatiles’). In order for PID to respond to a volatile, the photon energy of the lamp must be greater than its ionization energy (IE). ION Science PIDs are available with lamps emitting light of maximum energy of 10.0 eV, 10.6 eV, and 11.7 eV. This ...

How the Blockchain and Tokenization can Enhance the Oil and Gas sector
The blockchain was first used to support that most practical of activities: buying a takeaway pizza. Since then, it’s been through several development stages but, in many ways, much of this activity has focused on cryptocurrency for cryptocurrency’s sake, with attention devoted on the highs and lows of the price of key currencies. That’s all well and good, but the blockchain ...

Nitrogen for 3D Metal Printing?
Do you need Nitrogen for 3D metal printing ? When nitrogen is added in the metal printing process, it displaces oxygen and creates a completely inert atmosphere that does not interface with the laser or the material used for the finished product. N2 gas can significantly enhance the quality, reliability, and safety of the metal printing ...
