Automatic sample concentration dilution device of atomic absorption analyzer

摘要

Add a certain proportion of dilution solution to the sample solution used in the atomization device, and do not conduct the operation of artificial dilution of high concentration sample,The sample solution automatic stone returning device of the atomic absorption analyzer, which can greatly expand the range of effective concentration of each element through appropriate dilution of the stone returning proportion,In the sample concentration automatic dilution device of the atomic absorption analyzer including the sample atomization device (10) of the specified structure,The motor (20) installed at the lower end of the atomization device (10),(20) Wheel pump (30) started,(30) wow,The above pumps (30),(30) tube (32),(32) accept, according to the intermittent tilting action, according to the above pipe (32),(32) transfer the internal solution to a certain amount,The above tube (32),The first step is to connect the sample solution storage container (50) and the dilution solution storage container (60) respectively,The other Danes are the respective connecting tubes (54),(64) connect the mixing tank (70),The mixing tank (70) is the connecting pipe (54),(64) connected channel (70A),(70B) and one side are characterized by a circular mixing part (72),When analyzing the samples with high concentration and high concentration which do not conform to the law of rabert beer, it is not necessary to conduct concentration dilution through artificial analysis, which not only can reduce the time waste caused by this, but also can improve the reliability of the analysis value without medical analysis error on the analysis table.
