Abstract
A standard flame ionisation detector (FID) of the type used in gas chromatography experiments has been modified to enable flame extinguishing concentrations to be determined. Good agreement with Cup Burner data (a preferred fire extinguishing performance indicator) has been obtained for a number of gaseous Halon alternatives. The fact that only small quantities of these compounds (<1 g) are required for the test makes it an ideal tool for the assessment of novel compounds which may only be available in small quantities. The potential of the technique has been demonstrated by application to the study of novel phosphorous-containing compounds (PCCs) which were shown to be between two to four times more efficient than Halons.
