The Metrosep A Supp 19 product family stands out from the rest of the column line because of its superior separation qualities and high capacity.
This family exhibits the greatest peak symmetries and selectivities, as well as strong thermal, mechanical, and chemical stability, making it exceptionally durable and stable at higher flow rates and pressures.
The 150 mm version is regarded as the standard column for anion chromatography, as it reliably solves the majority of applications and is highly adaptable. Due to its large capacity, the Metrosep A Supp 19 - 150/4.0 separation column is ideal for demanding applications with intricate matrices.
The Metrosep A Supp 19-150/4.0’s exceptional separation qualities allow for a wide range of applications, including the following:
- Determination of standard anions and organic acids in boiler feed water to ensure the safe operation of power plants
- Determination of standard anions in pharmaceutical samples
- Determination of standard anions (fluoride, chloride, nitrite, bromide, nitrate, phosphate, and sulfate) in a wide variety of water samples
- Determination of standard anions and organic acids in complex sample matrices, e.g,. environmental or food samples
