Desiccant of test strip vials moisture content standard and detection method

Aug 07 , 2019

The test strip bottle refers to a packaging container for holding test paper. The pharmaceutical moisture-proof packaging material with a certain ability to isolate water vapor encapsulates the product, isolates the influence of external humidity on the product, and makes the relative humidity in the package meet the product demand. For the moisture content standard of the test paper bottle desiccant, refer to the moisture content standard of the desiccant in the YBB standard of the oral solid pharmaceutical low-density polyethylene moisture-proof combination bottle cap. The standard desiccant is mainly silica gel, macromolecular sieve or silica gel: macromolecular sieve (the ratio is 4:6) The mixture is predominant and the moisture content must not exceed 4.8%.

Silicone desiccant in the environment where the relative humidity does not exceed 75%, quickly remove the cap from the closed packaging bag, and take out 5~7g from it, and put it in the constant weight weighing bottle (W1), in the process (W2 ), in a 180 degree ± 10 degrees oven (from the opening of the cap packaging to the desiccant into the oven for a total time of no more than 5 minutes) to constant weight (weighing is W3), according to the formula, the moisture content must not exceed 4.8 %.

In the environment where the relative humidity does not exceed 75%, the macromolecular sieve desiccant quickly removes the appropriate amount of the bottle cap from the closed package, removes the desiccant in the cap with tweezers, accurately weighs W1, and places it in a 950-degree high-temperature furnace ( The total time from opening the capping bag to the desiccant into the high temperature furnace shall not exceed 5 minutes), drying for 1 hour to remove the crucible, and accurately weighing W2 after cooling, according to the formula, the moisture content shall not exceed 4.8%.
