Description
The price is for the base unit. To receive a commercial offer for the device in the working configuration, please contact the manager.
Liquid chromatograph “LUMACHROM®” with photometric / spectrophotometric / fluorimetric / spectrofluorimetric detection is designed for qualitative and quantitative determination of organic substances in complex samples by high performance liquid chromatography.
The block-modular principle allows you to create the optimal configuration of the device, depending on the tasks of the analytical laboratory – from routine to research.
The composition of the chromatograph “LUMACHROM®” includes:
- base unit, consisting of a pump, a loop dosing valve, connecting elements;
- detectors – photometric, spectrophotometric, fluorimetric and spectrofluorimetric.
Advantages:
- the versatility of the liquid chromatograph lies in a wide choice of detection methods, increasing the information content of chromatographic analysis with the simultaneous use of 2 detectors, and also in compatibility with any type of HPLC detector;
- block-modular principle allows creating an optimal configuration of a liquid chromatograph for solving specific user tasks;
- Precise, pulse-free eluent flow is ideal for microcolumn HPLC;
- chromatographic columns with an internal diameter of 2.1 mm of our own production minimize the cost of the mobile phase, increase the rapidity of the analysis, and reduce the cost of a single determination;
- the possibility of completing a liquid chromatograph with columns and pre-columns of any size, both micro- and analytical scale, of our own and / or alternative production, is realized;
- the independence of the modules allows them to be used as part of HPLC systems from other manufacturers;
- modern computer programs provide the ability to automatically collect and process data with subsequent generation of a report in a user-friendly form;
- the liquid chromatograph is accompanied by its own methodological support, while it is possible to adapt any existing and develop new HPLC methods;
- quality and fast service is guaranteed throughout the territory of the Russian Federation and the CIS countries.
Additional features:
- completion with any HPLC detector;
- implementation of chromatographic analysis with the simultaneous use of two detectors of different types;
- the use of micro- and analytical columns (with an inner diameter of 1; 2.1; 4; 4.6 mm);
- connection of the column thermostat;
- interchangeable loops for the dosing tap;
- implementation of a gradient elution scheme;
- use of fluorimetric and spectrofluorimetric detectors as liquid analyzers with the functions of a fluorimeter / spectrofluorimeter / photometer / spectrophotometer, etc. (for example, with a K-10 cuvette).
Areas of use
- ecological and sanitary control;
- control of safety and quality of food products and raw materials;
- veterinary medicine, feed production;
