Excellent equipment with good reproducibility.
Rating: 4.3

  • Application Area: Meat and dairy products

"Sensitivity and reproducibility are sufficient for our work. The software is easy-to-use and intuitive and maintenance is also quite easy. Problems arose after improper preservation of the instrument, but a service engineer helped fix the problem. Sufficiently long-term sample preparation of meat and dairy products."

Convincing due to its reliability, accuracy and time efficiency.
Rating: 4.7

  • Application Area:Amino acid analysis of freeze dried samples from plants

"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."

Overall, a very stable and easy-to-use amino acid analyzer.
Rating: 5.0

  • Application Area:Analysis of physiologic fluids

"We replaced our Biochrom 30 instrument with a new ARACUS this year and have been using it almost daily for ~3 months. Overall, it is very stable and we have not had any major issues thus far. Sensitivity and reproducibility are sufficient for our clinical diagnostic work. The software is easy-to-use and intuitive and maintenance is also quite easy. Follow up care with membraPure has also proven to be excellent, as we are continuing to learn the nuances of the instrument and attempt to optimize some protocols."

Very easy to use, very responsive after-sales care.
Rating: 4.3

  • Application Area:Analyzing food and human blood samples

"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."

A very good device.
Rating: 4.0

  • Application Area:Analysis of amino acids in plant hydrolysates and free amino acids

"Since 2014, we have been using ARACUS to analyze amino acid composition in various plant species. What's good about this amino acid analyzer? Above all, high sensitivity and excellent reproducibility. The device is easy to use, with a user-friendly interface for management. It allows you to conduct amino acid analysis without problems in all samples (at least until we encountered unresolved problems)."

Outstanding equipment and service.
Rating: 5.0

  • Application Area:Amino acid analysis of freeze dried samples from plants, insects, and fish

"The ARACUS system is great for easy analysis of amino acids in different tissues (physiological analysis). The machine is running very reliably. Using the physiological standards provided, easy identification and quantification can be performed. It is very important to perform a deproteinization step using the sample preparation kit from membraPure before analysis and filtration of samples through 0.22 µm filter. Great separation of amino acids in extracts can be obtained from different freeze dried material of plants, insects, and fish. The analysis of amino acids with ARACUS is easier and more convenient compared to the ninhydrin pre-column derivatization. Furthermore, though we haven’t had any problems, the service has been very helpful, and we found the company very understanding of the needs of the scientific community."

  • Application Area:Development of analytical methods for mould fungi identification by amino acid profile

"We have been using ARACUS since 2012. The initial focus was the improvement of the detection sensitivity for the identification of different types of mould fungi by analyzing their amino acid profile in a research project. We worked closely with the application specialists and finished the project successfully. Within the last years, we were analyzing profiles from food without any significant trouble with our ARACUS."

Review date: 26 Mar 2020 | ARACUS – Amino Acid Analyzer

ARACUS works on the principle of golden standard, the post-column derivatization with ninhydrin, and the detection at 440nm and 570nm using maintenance-free LED photometers.

With a separation of more than 50 amino acids by cation exchange chromatography and a detection limit of < 2 nmol/mL, ARACUS offers the customer a wide range of application fields:

  • Determination of free/physiological amino acids in blood plasma, dried blood spots, serum salvia, and urine (e.g. New Born Screening)
  • Determination of hydrolyzed amino acids in food, beverages, and feedstuff
  • Determination of biogenic amine for the investigation of metabolic processes (plants animals, humans)

ARACUS advantages:

  • Detectors with maintenance-free LED technology (440 & 570 nm) - no UV/VIS lamp degeneration and lamp exchange
  • Chloride-free and citrate-free buffer system - Less aggressive to the components of the liquid handling tubes, fittings, and connection
  • Small eluent consumption - About 200 µL/min in analysis mode
  • High sensitivity of amino acids and a choice of two sensitivity detector levels
  • Level sensors for eluents - Warn the user if the needed fluidic volume is too low for the planned analysis
  • Easy access to all components of the entire system
