THPI elutes as a single peak in just over 2 min; the response is sufficient for detection of 0.2 ng of THPI. Results from triplicate determinations at each spike level (0.05, 0.10, and 0.20 ppm THPI in milk) gave recoveries between 70.0 and 87.7 % (Table 1). Table 1 Recovery of THPI from spiked mil
