Description
Technical field
The present invention relates in heavy metal analysis field, more particularly to a kind of full-automatic online Element detection instrument.
Background technology
At present, protective awareness more and more higher of the people to environment, it is proposed that various environmental practices, in environmental protection, to gas
Concern also more and more substantially, and composition and dust granules in gas are also a lot, and this is accomplished by being analyzed gas detection
To recognize the composition in gas, and gas is made up of the mixing of various gas, and various metal units are moreover also included in gas
Element and heavy metal element, both knowing about can damage when heavy metal element is exceeded to biology.In order to not make the heavy metal in gas
Element is exceeded, it is necessary to be analyzed detection to the heavy metal element in gas, makes exceeded gas by being discharged after purification, does not make
Into the gaseous contamination in environment.
Atomic Absorption Spectrometer can play a part of detection to the heavy metal element in air, in Atomic Absorption Spectrometer
In, the light from the full cathodoluminescence lamp (holocathodelamp) as light source is decomposed into spectrum by spectroscope, the light
The light of spectrum reaches detector.Detector signal voltage be decided by the element type of full cathodoluminescence lamp, the characteristic of spectrometer and
The spectrum sensitivity characteristic of detector.
In heated chamber type Atomic Absorption Spectrometer, sample is placed in graphite-pipe (heating tube), pipe is heated, made with this
Sample is heated to high temperature and is finally split into atom (atomization).Make the light beam of measurement by atom vapor therefore measure absorption
Rate.Therefore, when graphite-pipe is heated into maximum temperature, i.e., when sample atomization, graphite-pipe lights, the light for so sending
Line also reaches detector.
Because detection signal is too strong, including the detection signal of emitted light may make analog circuit saturation or may surpass
Cross the ceiling voltage that analog-to-digital converter can be converted.And when detection signal exceeds ceiling voltage, signal cannot be entered
Row accurate measurement.Due to this reason, optimum detection letter can be set by controlling detection signal multiplication factor before measuring
Number voltage (for example seeing JP-A-2002-71558).
The detection signal voltage is generally set to the 50-70% of the ceiling voltage that can be measured by Atomic Absorption Spectrometer.
The quantizing noise of noise or analogue-to-digital converters in view of the analog circuit used in Atomic Absorption Spectrometer, works as detection
When signal voltage is close to 100%, preferable signal to noise ratio can be obtained, but in order to avoid the light for being sent by graphite-pipe in addition makes inspection
Voltage signal saturation is surveyed, the voltage should step down to the 50-70% of maximum voltage.
According to the method for prior art, in the normal range (NR) of measurement request, for the light only phase sent from graphite-pipe
A specified nargin is hoped, and the permission determined by measurement request is not given for the Strength Changes of emitted light.Ripple
More long, gap is wider, atomization temperature is higher, and the intensity of the light sent by graphite-pipe is bigger.Therefore, by wavelength, seam
The detection signal voltage that gap width and atomization temperature are determined can exceed that maximum detection voltage.
In said case, gap width is narrowed by operator's manual type, realize the regulation to the voltage.But
When being that gap width narrows, the amount of light into detector tails off, therefore, signal to noise ratio will be deteriorated.
According to other method, in atomization operating process, multiplication factor is changed in response to detection signal.However, but former
About 1 second sonization duration, therefore, the requirement to circuit need to be improved, make the circuit that there is high sensitive, so that it can be responded
Multiplication factor is set in atomization.Additionally, ground multiplication factor claimed accuracy need to be set, therefore circuit cost is set to become expensive.
The Chinese patent of Application No. CN200410035052.9, including：One light source；One atomization part, is used for
By sample atomization；One spectroscope with gap and diffraction grating, for by the light line drawing one from the light source
Specific wavelength；One detector, the intensity for measuring the light by sample, to export an electric signal；One
Amplifier, for amplifying the electric signal；One memory cell, for storing detector signal voltage, signal voltage correspondence
In the group of all programmable of the atomization temperature of each measurement wavelength, the gap width in the gap and the atomization part
Close；One multiplication factor control unit, to measure all measurements that sample is used during being operated for basis and sample measurement
Wavelength, gap width, atomization temperature corresponding detector signal voltage controls the amplifier, makes it have optimal inspection
Survey device signal amplification factor, can solve the problem that problem above, but this kind of Atomic Absorption Spectrometer can not carry out on-line checking and
Online upload and preservation, reduces its practicality.
