GOOD LABORATORY PRACTICE for HPLC

Ensure that an organic solvent is flushed through the HPLC system and column at least once every 48 hours to kill unwanted microbial growth. Alternatively add a small amount of sodium azide to the aqueous solvent to inhibit growth. Note: Never allow a HPLC column or system to stand with water or buffer in it for an extended period of time.

Determination of β-Carotene in Supplements and Raw Materials

Use of HPLC System A vs HPLC System B. The method extracts carotene isomers efficiently. However, to accurately quantify β-carotene levels in products that contain elevated levels of α-carotene, a separate LC analysis was used to better resolve the α-carotene and β-carotene isomers. All test samples were initially analyzed using LC System A.
