QuattroPlex is the first Russian open multiplex platform for the quantitative and qualitative analysis of biomarkers by immunofluorescence analysis on magnetic beads. The detection technology copies the xMap technology, which allows analysis of several dozen analytes in a minimum volume. QuattroPlex benefits:

• • Multiplexing - diagnostics of up to 50 markers in one sample in one analysis
• • analysis of a wide range of markers (rheumatology, autoimmune diseases, HLA, cytokines, infections)
• • open system - use of any test systems based on magnetic coded microspheres
• • high sensitivity - possibility of qualitative and quantitative analysis
• • design that requires minimal desktop space
• • possibility of use in mobile laboratories.

Specifications:

• • Registered size of microspheres, microns — from 0.5 to 100;
• • 3 fluorescence registration channels;
• • fluorescence excitation wavelengths, nm — from 380 to 850;
• • wavelengths of fluorescence registration, nm — from 450 to 950;
• • detector - CMOS matrix;
• • sample volume, µl — from 30 to 60;
• • number of test samples per load — 1 (in a chip);
• • time for analysis of one sample, sec — 4;
• • Results management and analysis software - QuattroPlex results management and analysis software, compatible with Win/Linux;
• • interfaces for connecting to a laptop/PC — Internet/Wi-Fi;
• • dimensions W×D×H, cm — 20×20×30.

Delivery set:

• • system of multiplex analysis of biomarkers QuattroPlex;
• • starter set of consumables;
• • computer, keyboard, mouse and monitor.

The analyzer allows you to determine the content of sulfur and nitrogen in oil and petroleum products (diesel fuel, gasoline, kerosene, gas oil and any distillate petroleum products), hydrocarbon gas, liquefied petroleum gas (LPG), natural gas, liquefied natural gas (LNG), chemical synthesis products, biological materials by ultraviolet fluorescence and chemiluminescence. The analyzer is a proprietary development of NPO "SPEKTRON". The device is manufactured in St. Petersburg mainly from domestic components. There is a conclusion of the Ministry of Industry and Trade on the production of products in the territory of the Russian Federation. The analyzer is designed to determine: - mass fraction of sulfur in accordance with GOST ISO 20846-2016, GOST 34712-2021, GOST R 56866-2016, GOST 34237-2017, ASTM D5453-19, ASTM D6667-21, ASTM D7551-15, ISO 20729-17 ; - the mass fraction of nitrogen in accordance with ASTM D4629-17. A wide range of concentrations: from ultra-low to high. Modular principle: Each detector is a separate module. The device is equipped individually for each specific task. The possibility of simultaneous determination of sulfur and nitrogen in the analysis process. The principle of operation of the analyzer is to burn the test sample in an oxygen-enriched atmosphere or air at a temperature of 1050 ° C. The sulfur dioxide (SO2) and nitrogen oxide (NO) formed during combustion are transferred by carrier gas to the detection units with preliminary removal of water vapor, on the desiccant, and soot, on the filter. Determination of sulfur is carried out by ultraviolet fluorescence. Determination of nitrogen by chemiluminescence.
