We offer expert laboratories of physicochemical methods of analysis a gas chromatograph with a quadrupole mass spectrometric detector «MAESTRO-αMS». Quadrupole GC-MS «MAESTRO-αMS» is in demand for targeted research (screening) and non-targeted search. In targeted studies, it is necessary to detect given target compounds in samples of various nature and origin at the level of residual amounts, for example, several picograms of the target compound in the injected 1 μl of liquid sample. Most often, targeted research is carried out in the following areas of laboratory screening: ecology, food safety, clinical monitoring, narcology, doping control, production control of various raw materials. In targeted studies, it is often required not only to confirm the presence of a compound in a sample, but also to determine the level of its content quantitatively, since both the list of target compounds and the permissible level of their presence in the sample are specified by regulatory documents. Quantitative analysis requires standards for the substances you are looking for. When conducting a non-target search, as a rule, it is required to analyze a sample of unknown composition, in other words, to find as many compounds as possible in the sample and identify (identify) each of them. Since the identification of a detected compound is carried out by comparing its experimental mass spectrum with the spectrum of a pure substance obtained under standard conditions, this task requires reference libraries of mass spectra of pure substances, as well as tools for working with mass spectra, for example: algorithms for cleaning experimental mass spectra from background and spectral noise (mass spectrum deconvolution algorithms), library search and comparison algorithms. An off-target search is called a qualitative analysis, since the researcher is primarily interested in the list of detected substances, and not in the quantitative assessment of their content in the sample. When creating MAESTRO-αMS, we took into account our own many years of experience in operating imported analogues. We have made the device inexpensive. We have made the device compact: The modern design of the device made it possible to make the MAESTRO-αMS really compact, so that the device occupies the smallest possible area on the laboratory table. The layout of the device allows you to remove the ion source on the front flange for cleaning and replacing the cathodes, if necessary. We have reduced the cost of operation: When developing the MAESTRO-αMS, we sought to increase the resistance of the device to sample matrices and use a minimum of consumable materials in order to eliminate downtime for maintenance and replacement. As a result, we have created an extremely stable ion source and a perpetual photomultiplier detector. We have created special software: Even at the first acquaintance with the software, it becomes obvious that being in the window of each button and each parameter to be changed is expedient and logical. Our software product was created for the convenience of the operator, so we implemented the necessary and eliminated the unnecessary. We used the principle of one active window, in which the operator moves sequentially step by step, performing hardware settings, setting the data collection method, subsequent processing algorithms, templates for presenting the results. MAESTRO-αMS offers a wide range of scanning modes, built-in algorithms for working with mass spectral data, convenient unloading of initial data arrays for their processing in specialized software packages, graphics export for presentations and scientific publications. You can use several libraries of mass spectra at the same time, or create your own for your typical tasks. Finally, we provide a 5-day training course for professionals who want to understand the theoretical foundations of the method and their implementation in the hardware of modern quadrupole GC/MS. The volume and depth of presentation of the material from the developers of the device is intended to lay the foundation for the effective use of «MAESTRO-αMS» in the future. Some technical characteristics of MAESTRO-αMS: • Instrumental detection limit (SIM, OFN @272 m/z ) < 10 fg; • Scan modes: scan for selected ions, full scan in a given mass range, combined scan mode; • The number of simultaneously connected libraries of mass spectra is at least 10.

The hydrogen generator is equipped with its own microprocessor, with which you can control the operating modes of the device. It is microprocessor control that determines the autonomy of the device. Moreover, this allows you to control the basic and technical parameters of the device (pressure, flow rate, level of water poured into the tank, tightness of gas lines, electrolyzer current). For the manufacture of gas lines, exclusively inert materials are used. Technical specifications:

The device is equipped with a four-button keyboard, which is used to set parameters and control. The generator can operate in continuous mode for a long time. For refueling, especially pure or double-distilled water is used, and refueling can be done without turning off the device, on the go. Their advantage is that they significantly reduce, or even completely eliminate, the use of bottled gases to power chromatographs and gas analyzers. For nutrition, mainly double-distilled water is used, the quality of which must be no lower than grade B water according to OST 11.029.003–80, and the electrical resistivity must be no less than 1 Mohm x cm.

The devices operate from a single-phase AC electrical network with voltage from 187 to 242 W, frequency (50±1) Hz. Maximum safety of devices is achieved due to the absence of such a supply of substance in them, which could fill a chromatograph or laboratory in a short period of time. The performance of the device eliminates the occurrence of explosive situations, so the generator is considered safe to use.

The flow regulator consists of the following parts: Body. It includes a connector for connection to the control controller and fittings for connecting the input and output gas lines. Calorimetric converter. Due to the heating of the gas along the flow section, the temperature difference is determined. The actuator (solenoid valve). The control board. A system of elements responsible for converting the signals that the user submits. TECHNICAL CHARACTERISTICS OF RD The gas pressure at the inlet is (0.4 + 0.04) MPa.

Pressure ranges — from 0.001 to 0.40 MPa with a discreteness of 0.0001 MPa. The deviation of the carrier gas flow rate from the average value is + 1.5% in the flow range from 50 to 100 ml/min and + 0.5 ml/min in the flow range from 3 to 50 ml/min. Relative deviation of the average steady-state gas flow rate from the set value in the range from 3 to 100 ml/min: + 2.5%, but not less than 0.5 ml/min; from 100 to 200 ml/min.: + 5%; from 200 to 800 ml/min.: + 10%. The gas pressure at the inlet is (0.4 + 0.04) MPa. The deviation of the regulated output pressure of the regulator from the set value is not more than 1%.

The generators are designed to supply analytically clean air to flame ionization detectors and gas analyzers. They are available in two versions depending on performance and output pressure. Thanks to the presence of a system of catalytic purification of air from hydrocarbons, the generator can significantly improve the accuracy and sensitivity of chromatographic analyses.

The NV-1500 LX-O are specialized laboratory tables on a reinforced metal frame with a countertop width of 1500 mm. They are designed to accommodate heavy instruments, such as chromatographs or other analytical equipment. In the upper right corner of the table there is an electric panel with two sockets. Both sockets with grounding and shutters are designed for current up to 16 A and voltage up to 250 V. Working surface material: porcelain tile. It is moisture-resistant and perfectly withstands high temperatures. It is resistant to prolonged exposure to concentrated acids, alkalis and organic solvents. It has limited resistance to hydrofluoric acid. This is one of the most popular types of countertops for laboratory furniture. The tables have a metal frame painted with durable powder paint. The side laminated panels (chipboard with a thickness of 16 mm) are edged with a durable PVC edge with a thickness of 2 mm, which increases their impact resistance and mechanical strength. The legs of the table are adjustable in height within two centimeters, allowing you to place it even on a rather uneven floor. Dimensions of the table when assembled: 1500×700×850 mm. It is designed for standing work.

It can be used as a primary source of carrier gas, since it is equipped with an additional gas purification system. This device is especially relevant when, for some reason, helium is not available to the consumer (for example, when working with a thermal conductivity detector - an accident). Due to the high thermal conductivity of hydrogen, TTP operates with significantly greater sensitivity than helium.

The PA-1 single-channel portable aspirator is based on the PC-1 portable compressor. It provides air aspiration with a flow rate from 0.1 to 0.8 l/min. The aspirator is powered by an integral battery.
