农产品质检站实验室仪器配置清单

Core Viewpoint - Agricultural product quality safety is the first line of defense for food safety, with agricultural product inspection laboratories being the core battleground to safeguard this line [2][3]. Group 1: Importance of Inspection Laboratories - Agricultural product inspection laboratories are essential for accurately controlling key indicators such as composition, harmful substance residues, and physicochemical properties [2][3]. Group 2: Common Instruments and Their Uses - pH Meter: Measures pH value [4] - Conductivity Meter: Measures the conductivity of electrolyte solutions [4] - Liquid Chromatograph: Qualitative and quantitative analysis [4] - Gas Chromatograph: Qualitative and quantitative analysis [4] - Automatic Potentiometric Titrator: Acid-base, redox, precipitation, and complex titrations [4] - UV-Visible Spectrophotometer: Measures the absorption of substances at different wavelengths for quantitative analysis [4] - Atomic Absorption Spectrophotometer: Quantitative analysis based on the absorption of characteristic radiation by ground state atoms [4] - Karl Fischer Moisture Meter: Measures moisture content [4] - Fourier Transform Infrared Spectrometer: Qualitative and quantitative analysis [4] - Colorimeter: Measures the color of agricultural products [4] Group 3: Additional Instruments - Ion Chromatograph: Qualitative analysis [5] - Fluorescence Spectrophotometer: Measurement of elements that easily form hydrides or gaseous components [5] - Refractometer: Measures refractive index [5] - Kjeldahl Nitrogen Analyzer: Measures nitrogen content in proteins [5] - Mycotoxin Testing Instruments: Measures aflatoxin content [6] - Sulfur Dioxide Testing Instruments: Measures sulfur dioxide concentration [6] - Fiber Analyzer: Measures fiber content [6] - Fat Analyzer: Measures fat content [6] Group 4: Comprehensive Detection System - The instruments cover basic physicochemical indicators (e.g., pH, moisture, sugar content), critical safety indicators (e.g., pesticide residues, aflatoxins, heavy metals), and nutritional components (e.g., amino acids, fats, fibers), creating a comprehensive detection system [6].
