HPLC Method for Analysis of Neurotransmitters on BIST B+ Column

High Performance Liquid Chromatography (HPLC) Method for Analysis of Phenylephrine, Epinephrine, Norepinephrine

Epinephrine and norepinephrine are key neurotransmitters and adrenal hormones naturally produced by the body to generate the fight-or-flight response, and synthesized by pharmaceutical companies to treat a host of issues, such as allergic reactions and low blood pressure. Phenylephrine is a related, synthetic compound made to treat low blood pressure, congestion, and hemorrhoids.

Using SIELC’s newly introduced BIST™ method, these three similar neurotransmitters, which protonate in water, can be retained on a positively-charged anion-exchange BIST™ B+ column. There are two keys to this retention method: 1) a multi-charged, negative buffer, such as Sulfuric acid (H2SO4), which acts as a bridge, linking the positively-charged amine analytes to the positively-charged column surface and 2) a mobile phase consisting mostly of organic solvent to minimize the formation of a solvation layer around the charged analytes. Using this new and unique analysis method, Epinephrine, norepinephrine, and phenylephrine can be retained and UV detected at 200 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.
