Description
Technical field
The utility model relates to a kind of portable magnesium sulphate detector.
Background technology
Monosodium glutamate is people's daily life flavouring commonly used, is a kind of column crystal of white granular.Magnesium sulphate is the crystallization of colourless quadrangular prism shape or granular crystal, and from the appearance, to monosodium glutamate and similar, naked eyes are difficult the resolution extremely.Higher economic interests are pursued in order to reduce cost by illegal businessman in recent years, add excessive magnesium sulphate in monosodium glutamate, and sodium glutamate is seriously not up to standard.
The magnesium sulphate bitter, soluble in water, it is a kind of bulk cathartic, if people take concentration excessive Adlerika, can cause the eater to dewater, poison, Symptoms is stomach severe pain, vomiting, diarrhoea, expiratory dyspnea mydriasis, bladder and kidney is unable, shock, severe person's bradycardia, blood pressure drops, lethargic sleep, stupor; Suck for a long time low dose of magnesium sulphate, can cause constipation and paralytic ileus.Therefore, for ensureing the healthy of the people, check in the monosodium glutamate content of magnesium sulphate severely most important.
Stipulate among the GB/T8967-2000 that State Bureau of Technical Supervision implemented on September 1st, 2000 that sulfate is (with SO in the monosodium glutamate
4 2-Meter) content is not more than 0.05%.The mensuration of sulfate is to use the barium chloride precipitation method in the GB, and the method also needs number of chemical reagent and various glass apparatus except the exact instrument such as needs electronic balance.When the barium chloride precipitation method detect, when colorimetric, need carry out visually than turbid, if the sample hose turbidity is not higher than the standard pipe turbidity, be equal to or less than 0.05% with regard to sulphates content in the interpret sample.The mensuration of sulfate is to use the barium chloride precipitation method in the GB, and the method can not accurately detect the content of magnesium ion.When more accurately detecting the content of magnesium sulphate such as need, usually adopt the atomic absorption spectrophotometer (AAS) method to detect the accurate content of magnesium ion, the method also will have atomic absorption spectrophotometer (AAS) and support equipment (such as acetylene cylinder, acetylene gas etc.) except using number of chemical reagent and glass apparatus.Metalization of skin is expensive, and domestic about 120,000.
Whether barium chloride precipitation method detecting the contet of sulphate content exceeds standard, and error is large, wastes time and energy.The atomic absorption spectrophotometer (AAS) method is higher to equipment requirement, complicated operation.No matter be the barium chloride precipitation method or detect magnesium sulphate content with the atomic absorption spectrophotometer (AAS) method, all need to prepare number of chemical reagent, increase testing cost, detect the result and need at least three hours from sampling during detection, length consuming time, also need simultaneously the operator to have certain professional knowledge and stronger operative skill, the discrimination method that sulfate is commonly used is the method with the barium chloride precipitation, this large time of method error grows up to this height, needs number of chemical reagent and glass apparatus, and the atomic absorption spectrophotometer (AAS) method detects the content of magnesium ion, the result is accurate, but complicated operation, the time is long, and cost is high.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of portable magnesium sulphate detector that carries out qualitative discriminating to mixing magnesium sulphate in the monosodium glutamate, and this detector is easy to detect, simple to operate, be easy to carry and move, and testing cost is low, detection speed is fast.
Technical solution of the present utility model is:
A kind of portable magnesium sulphate detector, comprise micro-wave oven, its special character is: be placed with glassware in micro-wave oven, the diameter of described glassware is 90mm-150mm, highly is 18mm-22mm, is provided with handle at the micro-wave oven end face, in the micro-wave oven side hinged hinged, be provided with telescopic lever at the hinge frame, be provided with roller in the micro-wave oven bottom, be provided with the timer of power light, starting switch and band warning at the panel of micro-wave oven.
The beneficial effects of the utility model are: by microwave heating, make the magnesium sulphate in the monosodium glutamate that contains magnesium sulphate lose water of crystallization, after magnesium sulphate loses water of crystallization, become white particles, this granule and monosodium glutamate particle have obvious difference; Magnesium sulphate is dissolved in self water of crystallization, and makes most of magnesium sulphate and small part monosodium glutamate be gathered in container bottom when losing water of crystallization in addition, with the monosodium glutamate particle of dispersing significant difference is arranged also, thereby is judged whether have magnesium sulphate to exist in the monosodium glutamate.In glassware, add 20-50 gram monosodium glutamate sample to be detected during each the detection, carry out 2-6 minute thermal treatment after starting micro-wave oven, if glassware bottom and edge have the cohesion adsorbate to exist, or the white powder that exists between the monosodium glutamate particle, then mixed magnesium sulphate in the monosodium glutamate; If glassware bottom and edge be without the existence of cohesion adsorbate, and between the monosodium glutamate particle without white powder, then do not mix magnesium sulphate in the monosodium glutamate.Owing to being provided with roller in micro-wave oven bottom and being provided with telescopic lever in the micro-wave oven side and being provided with handle at the micro-wave oven end face, being convenient to mobile and carrying; Volume is little, is easy to carry; Easy to detect, simple to operate, testing cost is low, detection speed is fast.
