Separation type: Bridge Ion Separation Technology, or BIST™
BIST Ionic Modifier Preparation
High Performance Liquid Chromatography (HPLC) Method for Analysis of m- Xylylenediamine (MXDA)
HPLC Method for Analysis of m-Xylylenediamine on a BIST™ B Column.
m-Xylylenediamine (MXDA) is a popular curing agent used on epoxy resins. Using SIELC’s newly introduced BIST™ method, MXDA, which protonates 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 MXDA analytes to the positively-charged column surface and 2) a mobile phase consisting mostly of organic solvent (such as MeCN) to minimize the formation of a solvation layer around the charged analytes. Using this new and unique analysis method, MXDA can be retained and UV detected at 210 nm.

| Flow Rate | 1.0 ml/min |
| Detection | UV 210nm |
| Class of Compounds | Amine, Aliphatic amine |
| Analyzing Compounds | m-Xylylenediamine (MXDA) |
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.
