When preparing your mixture, the goal is to raise the temperature of the liquid to between 90 and 99 degrees. The reason is that when the collector is instructed to measure the temperature of your specimen immediately following the test. If the temperature is outside of this range, it raises suspicion that the sample has been altered.
There are two ways to prepare QuickFix 6.2: a quick method that utilizes a microwave, and a slower process that warms your sample using body heat and a heating pack.
As a rule of thumb, use the quick method if you know when your test is going to be. Use the slow method if you don’t know when to expect it, and you need to carry the sample around with you.
