| 520 | 3 |a"At the request of NWQL, a study was initiated to improve the reproducibility of the results obtained from the new automated gas chromatography laboratory, where the instruments are controlled by an HP 1000 computer. The initial criterion was that the coefficients of variance for each chromatographic peak was to be 5% or less for ten consecutive injections. The conditions of operation were splitless mode injection and dual column chromatography. The standard compounds were pesticides and chlorobenzenes contained in the hexane and benzene eluates of the clean-up stage of aquatic samples. Also bromobenzenes and hexa-chlorobutadiene were included as these were surrogates added to actual samples. The reproducibility of the automatic injector was first checked and CV for two test sequences was less than 1%. Operating conditions were then altered as was the integration parameters and this resulted in CV's of 5% or less for 33 of the 36 compounds"--Abstract, page ii. |
