Precise Amino Acid Analyzers for the use in clinical laboratories

Determine amino acids for newborn screening, food and beverages and more

Our ARACUS systems deliver outstanding results for amino acid analysis in research. They work according to the gold standard of post column derivatization with ninhydrin, using maintenance free LED photometers. A separation of up to 44 amino acids in about one hour is possible. The ARACUS is available in 3 versions, suitable for your field of application.

Excellent system. Software is manageable. Support is outstanding. We use the instrument in a clinical diagnostic laboratory and have found it to be very reliable, requiring little maintenance. We do have some issues getting consumables into the US."

"We have been determining the free amino acids in plant samples with the ARACUS amino acid analyzer since 2010. From the beginning, we were won over by the very good service provided by the team from membraPure. The high accuracy and reproducibility of the measurement results should be emphasized, which is an advantage for long-term monitoring studies. The system works reliably and the provision of ready-made solutions and standards means that the amino acid analyzer is extremely user-friendly. Due to the fully automatic and time-efficient operation of the device, the determination of the amino acids is also very suitable for numerically extensive sample series."

"Replaced our 20 year old BioChrom30. Uses much less reagent and has nearly identical performance. Software is easy to use. Support has been excellent. Highly recommended."

"This analyzer is easy to use in terms of sample preparation, sample run as well as data analysis. The results are reproducible. However, we did run into several problems, such as SD card fault, pump fault, unstable pressure. The service team and engineer helped resolve the problems every time. In general I'm satisfied with their product and service. It would be better if there were local service support so that we do not have to go back and forth with Germany all the time."

FEATURES of our Amino Acid Analyzers

Reliable analysis results for a wide range of applications

Qualitative and quantitative analysis of amino acids is required for a wide range of applications. Our ARACUS systems are designed for use in clinics, quality control, the pharmaceutical and food industry as well as in research. The ARACUS AA analyzers use the most precise and reproducable methodology, with which you can get up to 44 AA with an “Retention time reproducibility (RSD)” of  less than 0.1%. Choose your desired configuration with the aracus lite, classic and advanced – depending on the complexity of your amino acid analyses.

FAQ

Amino acid analysis is used wherever the content of free/ physiological or protein-bound amino acids has to be determined. The fields of application range from diagnostics to quality control and research. Sample matrices are usually:

- blood plasma, blood serum
- saliva, urine
- spinal fluid
- Food, beverages
- animal feed

In the amino acid analyzer, ion exchange chromatography is combined with the HPLC technique. Samples are usually very complex in nature and amino acids, even ionic compounds without a specific absorption wavelength, are difficult to analyze using conventional HPLC methods. The combination of both techniques compensates for the disadvantages. Already due to extensive testing, further method developments are very short. This allows the user to routinely operate the system with little user intervention and ensures high sample throughput.
