Nitrogen sensitivity

Analytical standards are prepared for two purposes for fortifying control matrices to determine the analytical accuracy and for calibrating the response of the analyte in the nitrogen-sensitive detector. [Pg.363]

The partial pressure is calculated from the ion flow measured for a certain fragment by multiplication w/ith two factors. The first factor w/ill depend only on the nitrogen sensitivity of the detector and thus is a constant for the device. The second w/ill depend only on the specific ion properties. [Pg.106]

Reichert and Linckens [83] have reviewed gas chromatographic methods for the determination of nitriloacetic acid in potable waters. They point out that esterification of the nitriloacetic acid is required to enable it to be volatilised in the gas-liquid chromatographic column, and they compared a range of esterification reagents and conditions for simplicity and speed of operation. The method chosen involved treatment of a concentrated sample with a mixture of -propanol-acctyl chloride (10 1) and the resulting nitroacetic acid-propyl ester injected into a column, which was fitted with a nitrogen-sensitive detector. The detection limit for nitriloacetic acid in potable water is about lpgL-1. [Pg.269]

The product is very oxygen- and nitrogen-sensitive. The synthesis must be carried out under an atmosphere of pure argon (or helium) and the solvents must be argon-flushed before they are used. [Pg.71]

Least et al. reduced the sample size to 20 pi serum, plasma, or saliva, in a microscale procedure. The extraction was carried out with a chloroform-isopropanol solution of the internal standard, 3-isobutyl-l-methylxanthine. After alkylation with tetramethylammonium hydroxide and pentyl iodide, gas chromatography was carried out on a packed 3 OV-17 on Gas Chrom Q column, by temperature programming from 180°C to 260°C, and using a nitrogen sensitive detector. With the sample volume used, the background interference is equivalent to about 0.1 mg/litre, and 0.5 mg theophylline per litre can easily be measured. Between-run... [Pg.205]
