Calibration and control standards

General

As with almost all chromatographic analysis methods, calibration standards are required for quantitative analysis and the clear identification of the sample components for comparison measurements. We offer a number of different standard solutions for amino acid analysis, which can be used immediately after a simple, specified dilution. These standards, each with a content of 5 ml and a concentration of 1.0 to 2.5 µmol / ml, are simply diluted to the desired concentration with a sample buffer and can be used immediately. A combination of different standards is also possible. Delivery takes place at room temperature and storage before and after transport at -15 ° C. A lot-specific data sheet is enclosed with each standard.

 

In order to additionally check the quality of the analyses and the analyser, for the clinical use we offer control plasma in different concentration levels.

5-403-151

Physiological standard

The 35 most important free amino acids for metabolic analysis and applications in animal physiology, as well as food and fruit juice analysis. This standard is also very well suited for the determination of foreign amino acids in the production of pure amino acids or amino acid mixtures.
