Introduction: The multi-sample automatic solid-phase microextraction instrument is an instrument specifically designed for the determination of total dissolved solids or evaporation residues in the national standard method, which quickly evaporates water or reagents to a constant weight. Instead of traditional water baths, oil baths and ovens, the dissolved solids or evaporation residues in the sample can be quickly and easily obtained. The operating procedures and steps are greatly reduced, and the workload of the experimental operators is reduced. Features: 1. It comes with a high-temperature aging port, which can be used for aging and nitrogen purge of the solid-phase microextraction probe. 2. The insertion depth of the probe and the extension length of the coating can be adjusted through the program to meet the requirements of different experiments. 3. The solid phase microextraction function is equipped with 20 sample trays, suitable for 10mL or 20mL headspace bottles. 4. The sample tray has an independent magnetic stirring heating position, temperature control range: room temperature ~ 150 ℃, magnetic stirring speed: 0 ~ 1500rpm. 5. Liquid injection adopts airtight needle injection, the minimum injection volume is 1 microliter, and the injection volume is 500 microliters; the injection accuracy is <0.5%. 6. In the liquid sampling function, 110 sample positions are suitable for 2mL sampling vials. 7. Equipped with 6 cleaning bottle positions, suitable for 4mL sample bottles, and can customize the solvent bottle position and waste bottle position; Technical parameter: Number of repeated injections: No limit on the number of injections Movement mode: turntable Volume of quantitative loop: 1, 5, 10, 25, 50, 100, 250, 500 (unit: μL, optional) Maximum number of injections: 500μL Injection needle cleaning method: internal and external wall cleaning, unlimited times Position control accuracy: <0.3mm Minimum injection volume: 0.1μL
