The organic solvent mixtures quality control samples, generated by the syringe pump method, are evaluated by collaborative testing. The testing shows that the syringe pump method is adequate to generate uniform organic solvent mixtures. The interlaboratory differences contribute the largest part of the total experimental error, since the inaccurate determination of desorption factor by individual laboratories represents only a small contribution. It is concluded that interlaboratory error in the present study is largely due to errors in standard calibration curve determination, instrument calibration, and sample handling preparation.
