✦ Synopsis

The day-to-day precision estimated over eight days with four an octadecyl (C-18) cartridge. The purification device has the samples and three urine controls (LYPHOCHECK level 1 :lot following advantages: fast sample clean-up, accuracy, no cross 03000) gave a mean value of 4.27 mg/L with a SD of 0.1 9 and a CV contamination, high recovery with smaller sample size, of 4.55% (the label value of LYPHOCHECK level 1 is 4.1 mg/L [3.6-reproducibility, cost savings (less solvent consumption andglass-4.61).

ware and no more emulsion).

The system is flexibleand has already been applied to detection of the catecholamines with a "type 1" extraction column filled with Bio-Rex 70. Theophylline is purified with a "type 2" column using
