HPLC Method for Analysis of Fast Blue B Salt on BIST B+ Column
December 7, 2022
HPLC Method for Analysis of Fast Blue B Salt on BIST B+ by SIELC Technologies.
Separation type: Bridge Ion Separation Technology, or BIST™ by SIELC Technologies
Fast Blue B Salt is a multicharged basic dye with a variety of applications in chromatographic testing, including in thin layer chromatography and lipase activity testing. Using SIELC’s newly introduced BIST™ method, Fast Blue B Salt 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 analytes to the positively-charged column surface and 2) a mobile phase consisting of a majority of organic solvent (such as MeCN) to minimize the formation of a solvation layer around the charged analytes. Utilizing a step gradient to switch to a completely aqueous MP after 2 minutes allows for retention to occur while also preventing the method from being too long. Using this new and unique analysis method, Fast Blue B Salt can be separated, retained, and UV detected at 320 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.
