Method for identification of material and spectrometer determine their chemical composition and relative content according to the material spectrum is called spectral analysis, because of the merits of many other There is nothing comparable to this method: high sensitivity, good selectivity, easy operation, strong anti-interference ability and good accuracy, thus obtains the rapid development, has become an important analysis spectrometer laboratory equipment and widely used in the detection of air pollution, water pollution, food hygiene, etc. in the metal industry. The spectrometer consists of five parts: light source, sample processing system, wavelength selector, detector and signal processing system. The sample processing system is composed of a sample holder simple to sample by way of manual sampling for the development of automatic sampling, to provide accurate and stable sample, reagent and waste discharge, in order to obtain accurate test results.
In order to ensure the accuracy of the test results, it is necessary to use the automatic sampling system to provide accurate and stable samples. The flow of the sample can be changed according to the sample matrix, so as to eliminate the interference. The system shall be suitable for corrosive samples or abrasive samples containing particulate suspensions.
In order to ensure the efficient and smooth analysis process, it is necessary to discharge the atomization chamber.
When analyzing sensitive and easily damaged samples, the sample transfer device should try not to destroy the sample composition.
JOURNEY MAN Solution
The peristaltic pump has good sealing performance, wide flow range, with self absorption capacity and strong stability, in the transmission fluid, fluid and fluid hose contact, avoid pollution two in the transmission process, through the selection of corrosion resistant hose can be used to transmit all kinds of corrosive fluid, through the selection of wear-resistant hose for the transmission of grinding fluid. Peristaltic pump products with a variety of control methods, easy to integrate with the system control, real-time completion of intermittent flow injection and effusion discharge function. By replacing the hose, the same pump can be used to transfer different types of fluid to avoid cross contamination between the fluid. Peristaltic pump has a lower shear effect, and is more suitable for transporting sensitive and easily damaged samples.
Industrial injection pump products have a high degree of fluid transmission accuracy, liquid only with the closed pipe and syringe wall contact, to avoid the liquid in the process of transmission of two pollution, to ensure the accuracy of the test results.
Plunger pump liquid transmission products with high precision, life of 5 million cycles, no consumables, fluid transport, fluid contact with closed pipeline and pump chamber to avoid fluid pollution two in the transmission process, ensure the accuracy of the test results.
