L-3000 automatic amino acid analyzer Introduction: L-3000 automatic amino acid analyzer is a product that our company has been researching and developing for many years. Its launch has successfully broken the long-term monopolization of imported instruments in the post-column derivatization amino acid analyzer market. Once it was listed, it has won wide acclaim in the market. As a result, our company has also become the first company in China to successfully launch a post-column derivatization automatic amino acid analyzer. The instrument is designed according to the post-derivative principle of ninhydrin column, and is divided into hydrolyzed protein analysis system (sodium salt) and physiological body fluid analysis system (lithium salt), in line with national standard GB 5009.124-2016 "Determination of amino acids in food", "in feed" Determination of Amino Acids and Standards for the Determination of Amino Acid Analyzers. In order to meet the needs of amino acid analysis, our company uses special infusion pumps, autosamplers, detectors, post-column derivation systems, etc., which are specially designed for amino acid analysis, which greatly improve the resolution and detection limit of amino acid analysis. Repeatability. Features: 1) Adopting ninhydrin post-column derivatization method, in line with international standards and national standards 2) The hardware consists of two parts: the host and the post-column derivative system. The host can be used as a set of quaternary gradient LC system. 3) The autosampler has a patented ammonia removal system to effectively avoid the impact of ammonia on the baseline. 4) Special high temperature UV detector 5) After repeated optimization of the post-column derivation system, the dead volume and pressure fluctuation of the system are greatly reduced. 6) Low maintenance cost: long column life, reagent consumables price is equivalent to other imported brands of amino acid analyzers Technical Parameters: 1 pump 1) Quaternary low pressure gradient pump with pulsation less than 1% or 0.1Mpa 2) Flow rate range: 0.001ml/min-10.000ml/min 3) Flow accuracy: ±0.2% 4) Gradient accuracy: ≤0.1% (JJG) ≤0.06% RSD (ASTM) 5) Maximum withstand voltage 9000Psi 6) Automatic cleaning function of plunger rod, anti-sedimentation, stable performance and long service life. 7) Built-in four-channel online vacuum degasser 8) Material: SUS special alloy lining or titanium alloy lining. 2 Autosampler 1) Injection method: Both ring injection and variable injection mode are available. 2) Injection volume: 1ul-500ul 3) Reproducibility: The variation is less than 1% at 10 ul variable volume injection. 4) Memory effect: <0.01%. 5) Sample tray: two trays, 48 sample positions per plate, 1.5 ml sample vials. 3 separation unit 1) Column: sodium ion exchange column, 4.0*150mm (import) 2) Ion column protection column assembly 4 derivative units 1) Derivative method: ninhydrin post-column derivatization 2) Temperature setting: room temperature to 150 ° C (increment: 0.1 ° C). 3) Gradient temperature program improves separation and run time. 5 detector 1) Spectroscopic system: Aberrance concave diffraction grating splitting that is superior to filter-type spectroscopic. 2) Detection wavelength: 190-800 nm. 3) With a reference channel, the detection wavelength is always checked. 6 chromatography workstation It can realize the control of the instrument, the collection and processing of data. It can realize automatic cleaning of the system, complies with GLP/GMP rules, and can perform system checkability test, custom customer report and user safety verification.
