(II) main business of the issuer
The company is a third-party testing organization specializing in soil and groundwater. The testing scope includes soil, water quality, gas, solid waste, agricultural food and dioxin, covering the testing business related to environment and food safety from farmland to dining table.
The company established its first soil and groundwater testing laboratory in 2013. Since its establishment, the company has actively seized policy opportunities and expanded rapidly. It has successively established a number of laboratories and liaison offices in key areas such as the Yangtze River Delta, Beijing Tianjin Hebei and the Pearl River Delta, with a rapid growth in business scale.
With professional service ability and profound project experience, the company has served major projects such as "national detailed survey of soil pollution". It is one of 233 testing institutions in the first batch of "national detailed survey and testing laboratory list of soil pollution" issued by the Ministry of environmental protection. It is a testing institution with professional characteristics of soil and groundwater. (III) core technology of the issuer
1. Inspection and testing technology mastered by the company
The company insists on promoting long-term development with continuous R & D. after long-term R & D investment, the company has mastered a large number of mature inspection and detection technologies in the field of soil and groundwater detection. Especially for non characteristic pollutants and new pollutants, the company increased R & D investment and continued to accumulate innovative detection technologies. The main inspection and detection technologies and their practical applications are listed as follows:
Technical name, technology and technology, advanced technology and practical application.
Example of source item No
The corresponding standard has not been established for automatic entry into the country by purging and trapping
The detection limit of this method is low, and the methyl autonomous instrument for separating methyl mercury from other substances in the soil of renewable resource 1 in Jiading District has high sensitivity. The test results table source uses the analysis and development matrix of a mercury in the center, and then splits it into mercury: the linear range of methylmercury is in the project, etc
Steam, then atomic fluorescence between 0-200pg, the detection limit is
Detector detection 0.10 μ g/kg
A suitable extractant is used to extract the available state standard in Guishan mountain soil in Shilin County, which has not been established in the country. The detection industry usually only detects the available arsenic in the soil 2 of an agricultural land in an area; Then, the total arsenic was determined by atomic fluorescence, the investigation and evaluation of unspecified effective soil and the analysis of arsenic were carried out, and the analytical methods of luminescence spectrophotometer and inductance arsenic were studied. The method can be used safely, and the project coupled plasma mass spectrometer can determine available arsenic quickly
The detection is accurate and the detection limit is low
Use appropriate extractant to extract triethylamine from North China Pharmaceutical Company.Ltd(600812) soil, and take triethylamine from soil independently. The state has not established corresponding standard Co., Ltd. (analysis and research and development of preparation of 3 amine, and then check it with spectrophotometer).
This method can meet the quantitative detection requirements of soil measurement in general pharmaceutical factory, and the detailed investigation items of pollution status
The country has not established the corresponding standard for the determination of avidin in the soil of Hebei XingBai Pharmaceutical Co., Ltd. by liquid chromatography UV. Due to the large amount of 4 bacteriocin and ivermectin and ivermectin of this kind of pharmaceutical molecular group Co., Ltd., it is difficult to detect the liquid phase content of soil environmental bacteriocin by traditional methods, Through the retention time, the method has good reproducibility, quality status investigation, accurate qualitative analysis by chromatography, low peak detection limit, etc
Product external standard method
The corresponding standard has not been established in France by gas chromatography-mass spectrometry
Sulfuric acid in soil is the second standard for the determination of sulfuric acid in soil. This method has good reproducibility,
The detection limits of dimethyl sulfide and diethyl sulfate are low. The experimental results show the R & D amount of diethyl 5 acid in Dongwan village, Ningdong town. The linear range of diethyl 5 acid is determined by the retention time and the characteristic ions of gas chromatography of dimethyl sulfate and sulfuric acid flood discharge ditch polluted soil. The linear range of diethyl 5 acid is isospectral analysis method of soil evaluation project, the quantitative value of internal standard method is 0.25-10mg/ml, and the detection limit is
0.03mg/mL
The corresponding standard has not been established in the country for UV detection by liquid chromatography
The method has good reproducibility, Gr (2019) - 27
Furfural, autofurfural and 5-hydroxymethyl furfural in soil are rapid and simple, and the detection limit is low. According to the content of 6 and 5-hydroxymethyl in the contaminated soil of the parcel, the experimental results of the standard substance show that the retention time of the analyte of furfural in the preliminary investigation project of 5-hydroxymethyl is determined, and the furfural and furfural are in the range of 0.1 ~ 0.5
10. External standard of peak area μ Linear closing within g / ml
The measurement system is good; The detection limit of this method
Technical name, technology, technology, advanced technology and application examples of source numbers
It is 0.1mg/kg and recovered after standard addition
The rate was 81.6% ~ 103.9%
Determination of six in soil in China
Detection method of valence chromium content
When Diphenylcarbohydrazide is used, acetone and other harmful substances must be used
Hexavalent spectrophotometric method and flow analytical agent in soil. According to the type of hexavalent chromium soil in the test samples of 7-valent chromium content test and development method of Zhejiang Agricultural Department, the content agent studied by a sample delivery test method of different extraction colleges is selected to obtain the optimal solution; Test items, etc
The instrument is simple and easy to use
Automation can greatly reduce the analysis cost
Personnel workload
Using suitable extractant to extract the residue of existing analytical solvents in China
The method of taking solvent residue in water quality can detect the chemical composition
Stay; There are few kinds of suitable heating materials, and this method is
A variety of solvents are separated by 19 procedures in water quality. It is the first one that can simultaneously determine the mass number of 8 solvent residues of Jiangxi Lixin Pharmaceutical Co., Ltd. in soil, headspace / Gas Co., Ltd. plot analysis and development of 19 organic solvents and ion ratio value, and accurate chromatography-mass spectrometry. This method can identify the target compounds in the site environmental investigation, and the sample pretreatment is simple and convenient
Selective ion monitoring is adopted, with low detection limit and good accuracy,
Mode for high sensitivity detection, strong operability, and can effectively reduce
Matrix interference
