Separation type: Bridge Ion Separation Technology, or BIST™
High Performance Liquid Chromatography (HPLC) Method for Analysis of Acetaminophen, Dextromethorphan, Pseudoephedrine, Doxylamine
Nyquil is a combination of medicines used to treat headaches, fever, body aches, cough, runny nose, sneezing, and sore throat caused by allergies, the common cold, or the flu. Nyquil contains the active ingredients acetaminophen, dextromethorphan HBr, doxylamine succinate, and sometimes, phenylephrine HCl. Acetaminophen is a pain reliever and fever reducer. Dextromethorphan is a cough suppressant. It affects the cough reflex in the brain that triggers coughing. Doxylamine is an antihistamine that reduces the effects of the natural chemical histamine in the body. Histamine can produce symptoms of sneezing, itching, watery eyes, and runny nose. Pseudoephedrine is used to relieve nasal congestion caused by colds, allergies, and hay fever. It is also used to temporarily relieve sinus congestion and pressure. All active compounds of Nyquil can be separated in HPLC on a BIST B+ column. The analytical method uses acetonitrile (ACN) gradient and water with sulfuric acid (H2SO4) as buffer and UV detected at 210 nm.

Application Column
BIST B+
BIST™ columns offer a unique and effective way to achieve separations that were traditionally challenging or even impossible with other HPLC columns. With the use of a special mobile phase, these ion exchange columns provide very strong retention for analytes with the same charge polarity as the stationary phase, unlocking new chromatography applications. What makes BIST™ columns stand out is their proprietary surface chemistry, which results in superior selectivity, resolution, and sensitivity. These columns offer a simple, efficient solution for a variety of analytical challenges, making them an excellent choice for researchers and analysts across many different fields.
