Abstract

The invention relates to a rotary sampling device of a portable near-infrared spectrometer of an AOTF (acousto-optic tunable filter). The rotary sampling device comprises a rotary sampling table, a sampling cup, a compact block and a bracket, wherein the rotary sampling table is arranged on the bracket; the rotary sampling table comprises a shell; a round hole for containing the sampling cup is arranged in the shell; a rotary gear and a motor gear are arranged inside the shell; the rotary gear is in transmission connection with the motor gear; a to-be-tested sample is contained inside the sampling cup when needing to be detected; the compact block is adopted to press the to-be-tested sample, and then the sampling cup is put into the round hole in the shell of the rotary sampling table; and the sampling cup is paved inside a groove with a through hole immediately. The rotary sampling device of the portable near-infrared spectrometer of the AOTF is aligned at the non-circle center part of the bottom of a quartz cup along a detection hole; a test cup rotates under the drive of the rotary gear; and a lens of the portable near-infrared spectrometer of the AOTF immediately detects the to-be-tested sample in an annular area with a fixed radius, and can detect a plurality of groups of data.

Description

technical field [0001] The invention relates to a rotating sample measuring device of an AOTF portable near-infrared spectrometer and its application, belonging to the technical field of analytical chemical instruments. Background technique [0002] Modern infrared spectroscopy (NIR) analysis technology is a high-tech science and technology that has developed rapidly in the field of analytical chemistry in recent years. Near-infrared light refers to electromagnetic waves with a light wave range of 780-2526mm. Generally, the near-infrared spectrum absorption of organic substances in this area is mainly hydrogen-containing Group (OH, CH, NH, SH, PH) double frequency and combined frequency absorption, the main structure and composition of almost all organic substances can find signals in their near-infrared spectrum, and the spectrum is stable. Moreover, it is easy to operate, rapid in analysis, and reflects the state of the measured object in real time; it does not destroy th...
