The diluted sample gas also eliminates quenching effects (see question 5). The system dilutes the sample gas with nitrogen in a 1:50 ratio. Thanks to the excellent sensitivity of CVAF, a fairly high dilution ratio can be used. ...
Whether upgrading existing test cells or planning new installations, Sierra can develop custom products and systems or provide complete turnkey solutions. It also matches the customer requirements of today with tomorrow’s needs to guarantee a solution that can expand with the test of time. ...
Analytical laboratories confront a wide range of issues that can affect their data, such as resources, trained personnel, time constraints and traceability. New dilution and sample introduction accessory systems have been engineered to confront these issues. With these systems it is common to see calibration coefficients of > ...
Considerations when buying the new system BSK Labs processes a high volume of samples, including some with a limited shelf life. ...
New monitoring technology Gasmet Technologies, a Finnish manufacturer of emission monitoring instruments has launched a new continuous mercury emission monitoring system (CMM) based on the cold vapour atomic fluorescence (CVAF) measurement principle. The analyser is integrated in an air conditioned cabinet together with a vacuum pump, an automatic calibrator and a nitrogen gas ...
We’re delighted to be able to provide an alternative exhaust sampling technology to expensive and often cumbersome full-flow CVS systems. ...
The exceptional system stability and the long path measurement cell provide instrumental detection limits as low as 5 ng/L using a sample volume of 5(H) jxL. The improved sensitivity of the FIMS permits sample dilution, therefore reducing the likelihood of an interference occurring with complex samples. ...
These systems fall into three categories: cold extractive, where the sample is drawn from the stack, rapidly chilled, then analysed; hot extractive, where the sample is analysed when hot; and the dilution system, where the sample is diluted to avoid the need to remove water ...
Representative samples were collected with a newly developed source dilution sampling system after an aging process designed to simulate atmospheric dilution and cooling conditions. Samples were analyzed with established procedures and compared between the measurements taken from a baseline ...
