Tablets of famotidine, an anti-ulcer compound, were subjected to stress conditions in pack. Figure 9.34 indicates the profile obtained from analysis of an extract from the stressed tablets by LC-atmospheric pressure chemical ionisation mass spectrometry (APCIMS). The structure of famotidine is shown in Figure 9.35.

Yu Ma and Bayne [198] differentiated different aroclors in soil using linear discrimination and analyses by electron-capture negative-ion chemical ionisation mass spectrometry. 

Examples of this type of herbicide are imazapyr, m-imazamethabenz, p-imazamethabenz, m,p-imazamethabenzmethyl, imazethapyr and imazaquin. Imazapyr has been determined at the xg/kg level in 0.1 M ammonium acetate extracts of soil by microwave-assisted extraction using electron capture negative chemical ionisation mass spectrometry [432]. High-performance liquid chromatography with UV detection at 250 nm has been used to determine imazapyr in methanol extracts of soil [433].

Stephanou [38] identified non ionic surfactants in non saline water by gas chromatography coupled with chemical ionisation mass spectrometry. Tertiary octylphenol and lauryl alcohol ethoxylates were qualitatively detected using their chemical ionisation mass spectra and the results used to compare the chemical ionisation and electron impact mass spectrometry techniques. 

Greaves and Unger [218] have used chemical ionisation mass spectrometry with positive ion chemical ionisation to qualitatively (full scan) and quantitatively (SRMS) determine tributyl tin, dibutyltin and mobutyltin in environmental waters. Detection...

Whilst on-line desorption chemical ionisation mass spectrometry (MS) has been used to analyse fermentation biosuspensions for flavones [11], the majority of MS applications during fermentations have been for the analysis of gases and volatiles produced over the reactor [12-15], or by employing a membrane inlet probe for volatile compounds dissolved in the biosuspensions [16-22]. It is obvious that more worthwhile information would be gained by measuring the non-volatile components of fermentation biosuspensions, particularly when the product itself is non-volatile, which is usually the case.
