Precision and accuracy of vaporization, as well as cold on-column injections, were studied using triglycerides as a sample of very high boiling point. Cold oncolumn injection gave by far the most reproducible results (with standard deviations of 1 to 3%) normalized on internal standard. A weak discr
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
