Alltech® OPA Amino Acid Columns
- OPA-HS for high-speed with protein hydrolysates.
- OPA-HR for high-resolution with physiological samples.
- OPA-HS (high-speed) columns are ideal for the study of
protein acid hydrolysates with very simple mobile-phase systems.
- OPA-HR (high-resolution) columns are ideal for applications that require more resolution than simple hydrolysates.
- OPA-HR gives baseline separation of most amino acids found in physiological fluids.
Alltech® Catecholamine Columns
- For routine analysis of indoles and catecholamines
- Reliable and inexpensive
With this column, easily resolve catecholamines under isocratic conditions at room temperature. A simple monochloroacetic acid mobile phase with varying amounts of sodium octyl sulfate and disodium EDTA controls the elution profile.
Alltech® Nucleotide-Nucleoside Columns
- Determine both nucleotides and nucleosides with a single column
With this column, separate seven common nucleosides or twelve common nucleotides using a buffer/methanol/tetrabutyl
ammonium phosphate gradient.
Alltech® Mixed-Mode Columns
- Separate hydrophobic and ionic species on a single column
Control ionization with buffer adjustments instead of ion-pair reagents
Alltech® Carbohydrate
- Cation Columns
- High efficiency separations using only water as the mobile phase
Sulfonated polystyrene resin in the calcium form
- Column heating required
