Public challenge is being more and more directed to insecticides and their residues in floor and floor waters. Water - one of many must haves of existence - needs to be stored fresh for guy and the surroundings. half I and II of this publication describe in an authoritative method all elements of recent research of insecticides in water by means of the resultant use of hyphenated strategies like GC-AED or HPLC-MS.

Example text

Yei-Ru and co-workers [21] examined a series of alkanes, alkenes and aromatics, reporting that the Hand C responses varied and depended on the original molecule. In another paper, Yei-Ru et al. [22] investigated a number of halogenated compounds and suggest the response is dependent on the number of halogens in the molecule. Rivierie et al. [23] and Jelink and Venema [24] examined numerous S-containing compounds. They found the response for S varied and suggested the response depended on the environment of the S element in the original molecule.

Equally important is the difference in response of the different compounds. 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.

It is not always convenient for analysts to use the unit of mass/sec as they are usually interested in detection limits for specific compounds. The absolute detection limit for a given compound (in pg) can be estimated from equation 1. Det. F. L.
