If you are looking for optimized HPLC method to analyze m-Xylylenediamine check our HPLC Applications library

For optimal results in HPLC analysis, it is recommended to measure absorbance at a wavelength that matches the absorption maximum of the compound(s) being analyzed. The UV spectrum shown can assist in selecting an appropriate wavelength for your analysis. Please note that certain mobile phases and buffers may block wavelengths below 230 nm, rendering absorbance measurement at these wavelengths ineffective. If detection below 230 nm is required, it is recommended to use acetonitrile and water as low UV-transparent mobile phases, with phosphoric acid and its salts, sulfuric acid, and TFA as buffers.
For some compounds, the UV-Vis Spectrum is affected by the pH of the mobile phase. The spectra presented here are measured with an acidic mobile phase that has a pH of 3 or lower.

HPLC Method for Separation of Amines on BIST B and BIST B+ Columns by SIELC Technologies

Separation type: Bridge Ion Separation Technology, or BIST™ by SIELC Technologies

m-Xylylenediamine (MXDA) is a popular curing agent used on epoxy resins. 2,4,6-Tris(dimethylaminomethyl)phenol is another amine-based curing agent used on epoxy resins. Using SIELC’s newly introduced BIST™ method, these amines can be retained and separated on a positively charged, anion-exchange BIST™ B or BIST™ B+ column. The surface chemistry of BIST™ B+ columns are designed to have stronger ionic retention capabilities, resulting in the marked increase in retention compared to BIST™ B columns.

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 dipeptide 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, these two amines can be UV detected at 210 nm.

HPLC Method for Separation of of Amines in Non Aqueous MP on BIST B+ by SIELC Technologies

Separation type: Bridge Ion Separation Technology, or BIST™ by SIELC Technologies

Dopamine is a key neurotransmitter and medical stimulant used to treat low blood pressure, low heart rate, and heart attacks. m-Xylylenediamine (MXDA) is a popular curing agent used on epoxy resins. 2,4,6-Tris(dimethylaminomethyl)phenol is another amine-based curing agent used on epoxy resins. Using SIELC’s newly introduced BIST method, these 3 amines 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 mostly of less polar organic solvent (such as IPA) to minimize the formation of a solvation layer around the charged analytes. This method uses an entirely non-aqueous mobile phase to drive BIST retention. The gradient starts with a high concentration of the less polar IPA to generate the initial BIST retention and progresses to the more polar MeOH to elute the longer-retaining amines in a reasonable time. Using this new and unique analysis method, these 3 amines can be retained and UV detected at 210 nm.
