Problems solved by technology

The traditional arc-excited one-meter or two-meter grating spectrometer usually uses phase plate recording, phase washing, photometry and other processes for spectral analysis. Its operating procedures are cumbersome, low work efficiency, high labor intensity, and easy to pollute the environment. Therefore, The majority of users are looking forward to the birth of a new type of arc-excited photoelectric direct reading spectrometer

Abstract

The invention discloses a multichannel integral circuit module, a multichannel circuit module group and a spectrometer. The multichannel integral circuit module provided by the invention comprises a plurality of photocurrent input channels, a plurality of integral and amplification circuit units, a processor unit and a module address coding unit, wherein a plurality of photocurrent input channels are respectively connected with respective integral and amplification circuit unit, and the outputs of all the integral and amplification circuit units are respectively connected with the processor unit. The module address coding unit is connected with the processor unit, and is used for setting the address information of the multichannel integral circuit modules, and the processor unit is used for collecting integral data of all the photocurrent input channels and reading the address information of the module address coding unit. The increase of the number of the channels can be realized by directly increasing the number of the multichannel integral circuit modules without redesigning an entire acquisition circuit. The multichannel integral circuit module has the advantages of high acquisition efficiency and easiness in integration.

Description

technical field [0001] The invention relates to the field of atomic emission spectroscopic analysis instruments, in particular to a multi-channel integrating circuit module, a multi-channel integrating circuit module group and a spectrometer. Background technique [0002] The arc-excited one-meter or two-meter grating spectrometer is an important branch of atomic emission spectrometry instruments. The characteristics of this instrument can directly analyze powder samples such as soil, rock, water system sediment and high-purity metal oxides in geological samples without chemical analysis. Digestion and dilution process, so as to avoid the content of some elements in the solution after digestion is diluted to reduce the analysis sensitivity, and it is easy to bring in uncontrollable pollution. [0003] For a long time, the arc-excited one-meter or two-meter grating spectrometer produced in my country has carried out geochemical prospecting nationwide in the geological field. ...
