Abstract

The invention provides an evaporation residue tester. An external hot-air conveying device is used for heating to evaporate test sample liquid in a detection box, namely heating the test sample liquid in a sealed space; evaporating dishes move up and down or left and right along with a rotary shaft and a lead screw under the driving of a motor to be butted with evaporating covers or are arranged on a pallet on a weighing balance for weighing; each evaporating cover is provided with a liquid feeding pipe for feeding samples, a gas feeding pipe for accelerating evaporation of inputted nitrogen and a gas discharging pipe for collecting waste gas; finally, residues obtained from evaporation are put on the pallet for weighing; the whole detection process is automatic without artificial participation. The evaporation residue tester has the advantages that the structure is simple, the operation is convenient, the error is less, obtained data is accurate, the needed cost is low and potential safety hazards are avoided.

Description

Technical field [0001] The invention relates to the field of residue testers, in particular to an evaporation residue tester. Background technique [0002] In view of the frequent occurrence of food safety issues in recent years, food packaging safety issues have also attracted attention. Chemical substances and metal residues contained in packaging containers will penetrate into food and affect human health. Therefore, it is necessary to detect the amount of insoluble residues in packaging containers. Particularly important. [0003] According to the GB / T9740-2008 general method for determination of evaporation residue of chemical reagents, the standard describes the equipment used in the detection of evaporation residue and the detection process. There are many instruments used in this experiment, which require relatively high accuracy, complex testing process, and large errors are prone to human operation. [0004] There are slight differences in the preparation of preparation s...
