Product Application Scheme

 

Application method of lead, cadmium and chromium in food(Graphite Furnace AAS)

Time:2022-11-14  Read: 47

Various limited metal components in food are determined under different spectral analysis with actual samples, in order to achieve the goal of comprehensive application of atomic absorption spectrometry. Select appropriate analysis conditions according to the analysis characteristics of each element, sample content, matrix composition and possible interference. It includes sample preparation, pretreatment, preparation of standard solution and preparation of calibration curve, selection of analysis conditions, operation method, result calculation, data processing and error analysis.

                  Standard basis: GB/T5009.12-2003/GB/T5009.15-2003/GB/T5009.123-2003/GB/T5009.123-2003 Determination of lead, cadmium and chromium in food
Theory
Graphite furnace automization is the most accurate and rapid method for the determination of harmful metal elements such as lead, cadmium and chromium in food. The detection limit of this method is 5u g/kg. It is a measurement method based on the light absorption of the ground state free atom at a specific wavelength. Its basic principle is to make the characteristic spectrum of the element to be measured radiated by the light source be absorbed by the ground state atom of the element to be measured in the steam when passing through the sample. Under a certain range and conditions, the degree of attenuation of the incident light absorbed is proportional to the content of the element to be measured in the sample, From this, the content of the elements to be measured in the sample can be obtained.
The ground state atoms of lead, cadmium, chromium and other elements in food selectively absorb the co radiation of the hollow cathode lamp, but the specific analysis conditions of each element are different. For example, the determination of lead is in an oxidizing atmosphere, but the determination of chromium requires a reducing atmosphere, and a high-performance hollow cathode lamp is required to obtain sufficient sensitivity. The sensitivity of these elements are different, so the concentration sequence is different when preparing the standard sequence, but they will not interfere with each other at a certain concentration, so their standard solutions can be mixed together for easy operation.

Reagents for sample digestion and constant volume
microwave digestion
Get 0.2 g~0.8 g (accurate to 0.001 g) of solid sample or accurately move 0.500 ml~3.00 mL of liquid sample to microwave digestion oven , Add 5 ml. nitric acid, and digest the sample according to the operation steps of microwave digestion. Refer to Appendix A for digestion conditions. After cooling, take out the digestion tank, and flush the acid on the electric hot plate at 140 ºC~160 ºC to about 1 ml. After the digestion tank is cooled, transfer the digestion solution to a 10 ml volumetric flask, wash the digestion tank with a small amount of water for 2~3 times, combine the washing solution in the volumetric flask, and dilute it to the scale with water, then mix it well for standby. Conduct reagent blank test at the same time
User manual
1.Install the hollow cathode lamp of the element to be measured, align the position, and fix the wavelength to be measured and the slit width
2.Turn on the current and fix the lamp current.
3.Adjust the position of the graphite furnace to make it in the best condition, and install the graphite tube.
4.Turn on the cooling water and nitrogen gas sources and adjust them to the specified constant flow value.
5.Setting of determination parameters of each element (refer to Table 5-3-3 Flameless atomic absorption method for lead, cadmium and chromium)
Result
1.Standard curve
Make the standard solution, and then operate according to the sample oxidation and extraction methods. Take 10uL samples respectively, inject them into the graphite furnace, measure their absorbance values respectively, and obtain the linear regression equation of the relationship between the absorbance value and the concentration. (The absorbance of blank is deducted).
2.According to the absorbance of the sample and blank, substitute it into the linear regression equation of the standard series to obtain the content (ug) of a certain element (lead, cadmium, chromium) in the sample solution
Calculation formula
X =(A0-A1)/m
X--Content of certain element (lead, cadmium, chromium) in the sample mg/kg
A1--Weight of certain element (lead, pot, chromium) in the sample solution for determination g
A0--Weight of certain element (lead, pot, chromium) in reagent blank solution ,LG.,
m--Equivalent sample quality of sample test solution for determination, g.
