(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 the 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 capability and profound project experience, the company has served major projects such as “national detailed survey of soil pollution”. It is one of the 233 testing institutions in the first batch of “list of national detailed survey and testing laboratories 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 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 method has low detection limit and high sensitivity for the separation of methylmercury from other substances in the soil of reclaimed material 1 in Jiading District. The test results show that the matrix is developed by the analysis of mercury in the center, and then cracked 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
Using appropriate extractant to extract the available state standard in Guishan mountain soil in Shilin County, which has not been established in China. The detection industry usually only measures the available arsenic in the soil 2 of an agricultural area; Then, the total arsenic was determined by atomic fluorescence, the effective state of soil was not clearly investigated and evaluated, and the analysis of state arsenic was studied. 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
Triethylamine in North China Pharmaceutical Company.Ltd(600812) soil is extracted with appropriate extractant, and triethylamine in soil is taken independently. The state has not established a corresponding standard Co., Ltd. (analysis and R & D of preparation of triethylamine, and then checked with spectrophotometer).
This method can meet the requirements of quantitative detection of soil pollution and detailed investigation items
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 were 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 contaminated 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 standard materials show that the retention time of analytical substance of furfural in the preliminary investigation project of 5-hydroxymethyl is determined, and furfural and furfural are in the range of 0.1 ~ 0.5
10, peak area, external standard 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 diphenylcarbazide is used for separation, 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 samples detected by the 7-valent chromium content detection method developed by the Agricultural Department of Zhejiang Province, the content agent studied by a sample sending detection 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
Suitable extractants were used to extract the residue of existing analytical solvents in China
The method of taking solvent residues in water quality can detect chemical compounds
Stay; There are few kinds of suitable heating materials, and the method is simple
A variety of solvents were 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 in soil, headspace / Gas Co., Ltd. plot analysis, R & D and ion ratio value of 19 organic solvents, and accurate chromatography-mass spectrometry. The target compounds were identified by site environmental investigation, and the sample pretreatment was 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
