Digital coal and rock analysis MSP 6000A digital coal and rock analysis system (SIPM) photomultiplier type photometer)

Main technical parameters and functions of MSP 6000A digital coal and rock analysis system:

1. Technical conditions and functions of MSP 6000A system silicon based (SIPM) photomultiplier tube photometerThe core photoelectric converters are single-stage TE cooled silicon (SiPM) photomultiplier tubes originally imported from Excelitas, Canada.With excellent performance of low noise, ultra-fast response and low crosstalk, and the internal LynXSiPM module is composed of a single-stage TE cooled detection head, a dc-dc power supply and a low-noise cross-impedance amplifier.The dynamic range and photon detection efficiency can be optimized.Sensitivity: 0.75v /nW @ 525nm (typ.);0.4v /nW @ 700nm (typ.), which can be extended to be used for detection of various wavelengths and fluorescence detection in the range of 350-950nm.

2, MSP 6000A system vitreous group reflectance artificial photometer detection technical conditionsVitrinite reflectance photometer test method, in line with GB/T 6948-2008 "vitrinite reflectance microscopy method for coal" and MT/T 1053-2008 "vitrinite reflectance photometer technical conditions" requirements.Manually confirm the test object and automatically test the reflectance of vitrine group. The test results can be used for arbitration.

The main peak was 546nm and the half peak width was 8 nm.

The transmittance is greater than 53%.

Detection accuracy: the data collection resolution is 1/65536, and the reflectivity can be resolved by 0.0001%.

The detection area is about 4um in diameter.A/D conversion pass rate 250K.

Automatic dark current correction.Can work steadily for a long time.

Linearity: any standard theory and measured value shall not exceed ±0.02%.

Stability: continuously test any standard sample for 30min, and the difference between the maximum and minimum fluctuation value shall not exceed the theoretical value of 2%.Statistical analysis is carried out for the vitrinite reflectance electrical signal of the measured coal, and the corresponding histogram is automatically obtained.Test results can be used for arbitration.
