Public predicament is being more and more directed to insecticides and their residues in flooring and floor waters. Water - one of many must haves of existence - should be stored fresh for guy and the surroundings. half I and II of this ebook describe in an authoritative manner all elements of contemporary research of insecticides in water by way of the resultant use of hyphenated options like GC-AED or HPLC-MS.

The optimum make-up gas flow rate for Pb was determined to be 300 ml min-I. Increasing the hydrogen reagent gas pressure from I to 7 atm resulted in a 25 fold linear increase in the emission intensity. 5 atm for all subsequent analysis. Combining the various factors for optimum response as well as on column injection, they determined the minimum detectable concentrations for 14 alkyl lead compounds. 1 pg. The values are compound dependent but are at least a factor of 10 less than had previously been reported using the most sensitive analytical techniques.

In addition the molten rubber from the fire scene was extracted with CH 2 Ch. The extracts from the GLSE were subjected to cleanup [I] and analyzed by capillary column GC/ECD, GC/MS and GC/AED. The AED was used to analyze the extracts for Cl, Br, C, N, S, and P. No halogens were detected in any of the extracts by the AED, which probably means that peaks detected by the ECD were caused by the ECD's poor selectivity. Also no response was observed in the P channel. Emphasis was placed on the N, S, and C responses detennined by the AED.

This is the prime cause of the peaks in the element specific carbon chromatogram having such poor shapes. However this does not influence the peaks measured on the P and S channels, an example of the specificity of the detector.
