Imported Amino Acid Analyzer (Mamobol)

V388s series fully automatic amino acid analyzer (Mamobol)Adopting the classic principles of cation chromatography separation, post column derivatization of trisodium glutamate, and visible light detection at 570/440nm, it is regulated by China, the European Union, and AOAC

The standard method for amino acid analysis. Compliant with international standards, Chinese national standards, European Pharmacopoeia, Chinese Pharmacopoeia, as well as GLP and 21CFR specifications, and compliant with international ISO and Chinese quality certification.

Special separation methods

Multi gradient separation mode (concentration gradient+pH gradient+temperature gradient)

On the basis of using concentration gradient combined with pH gradient separation, a temperature gradient separation function has been specially developed. This function is different from traditional column temperature box constant temperature heating or variable temperature heating, and adopts a fitting temperature control method,

The chromatography column is tightly attached to the column temperature box, and the stainless steel column tube is temperature controlled in real time using copper, a metal with a high thermal conductivity in the column temperature box. Different types and special amino acids are eluted at different stages within their elution time

The precise temperature control of the segment achieves the true function of temperature gradient elution, effectively improving the separation efficiency.

Breaking through traditional detectors

The third-generation micro diode photometer adopts wide bandgap semiconductor technology and micro LED light source based on nitride semiconductor, which has the advantages of high efficiency, high sensitivity, high brightness, fast response, and no energy attenuation

The detector of a traditional amino acid analyzer uses a halogen lamp as the light source, emits light from a tungsten filament, and then splits the light online through a filter or grating to obtain two wavelengths, 570nm and 440nm. However, the radiation flux of the 440nm channel is much higher

Below 570nm, the chromatographic peak responses of the two channels differ by several times, which has a certain impact on the quantitative results.

Excellent reaction unit

Adopting advanced UHT (Unidirectional Heat Transfer) technology, a layer of unidirectional thermal insulation film is added outside the tubular reactor, which has the characteristics of forward heat transfer and reverse heat transfer barrier

Point. The thermal conductivity efficiency of the V388 reactor has increased by 20% compared to the previous generation reactor, and the optimal reaction can be achieved without excessive derivative temperature. It has the advantages of high reaction efficiency and fast reaction speed.

In 2021, the German company Mamobol upgraded the existing V300 series amino acid analyzer. In addition to adhering to the technical advantages of the V300 series amino acid analyzer,V388sseriesImported Amino Acid Analyzer (Mamobol)By adopting more advanced UHT unidirectional heat conduction technology and third-generation LED detection technology, the efficiency of the reaction has been greatly improved, and the sensitivity of the detector has been further enhanced, thereby improving the overall performance of the instrument
