Mass spectrometer Autoflex II LRF20

Mass spectrometric complex with laser desorption / ionization MALDI-TOF Autoflex II LRF20 is designed for analysis of ions in a wide range of m/z; it provides detailed and accurate information on the molecular weight of the analyte; it allows analyzing a wide range of molecules - from smaller molecules, such as lipids and peptides, to polymers and intact proteins exceeding 100 kDa; it is indispensable in the analysis of non-volatile macromolecular compounds (proteins, carbohydrates, oligonucleotides) and small molecules (secondary plant metabolites, phytohormones, etc.).

HPLC Agilent 1260 Infinity II

The Agilent 1260 Infinity II High Performance Liquid Chromatograph is used to analyze mostly polar non-volatile compounds. With the help of the device it is possible to determine different classes of biologically active substances: in particular, secondary plant metabolites (phenolic compounds, flavonoids, anthraquinones, saponins, etc.), phytohormones (auxins, gibberellins, abscisic acid and its derivatives, cytokinins, etc.), and other biologically active substances of plant origin (alkaloids, sesquiterpene lactones, etc.).

The main technical characteristics of the Instrument

Four-channel plunger pump (up to 400 bar) with flow rate of 0.001-10 ml/min (step 0.001 ml/min) with solvent compartment. Solvent supply adjustment step: 0.001 ml/min. The pH range of the eluent is 1…11.5. Plunger volume: 180 μl.

Vacuum degasser for 4 channels with a capacity of up to 10 ml / min.

Autosampler / Block of automatic sampling / (100 samples up to 2 ml) with the ability to add an internal standard, dilute the sample and perform derivatization. The possible volume of the sample is 0.1…100 μl. Input accuracy of 1% (relative standard error for the sample - 0.1 μl).

Column thermostat (temperature range from 10 °C below room temp. up to + 80 ° C (in steps of 1°). The thermostat holds 3 columns up to 30 cm long. Temperature maintenance accuracy ± 0.15ºC The thermostat is equipped with a device for recording and reading information stored on the identification modules of the columns.

Diode-matrix detector (1024 photodiodes) with a wavelength range of 190…950 nm (1 nm discreteness), with automatically variable programmable spectral width of the slit (from 1 to 16 nm.), including the in-process of chromatographic analysis, with a high pressure cuvette. The detector has an integrated holmium oxide filter to check the correct setting of wavelengths and is equipped with a system of warnings about the need for timely preventive replacement of the light source. Noise level during operation of the spectrophotometric detector is 0.6 × 10-5 units of optical density.
