Introduction: The DTS-240 automatic solid phase extraction instrument is an instrument developed for the pretreatment of organic analysis that can automatically run the solid phase extraction method under unattended conditions. Automatically complete the whole process of solid phase extraction (column activation, sample loading, column elution, column drying, column elution, etc.), automatically complete functions such as column switching, and realize batch sample processing. The solid phase extraction instrument can be used in various food safety testing, agricultural residue monitoring, medicine and health, environmental protection, commodity inspection, tap water and chemical production laboratories. Features: 1. Column activation-loading-column elution-column drying-column elution, automatic completion of column switching and other functions, realizing batch sample processing 2. Dual sample position loading to achieve simultaneous activation, simultaneous loading, simultaneous elution and simultaneous drying of dual channels; according to the number of samples can be upgraded to four channels, six channels and eight channels 3. A single machine can continuously process 24 samples, automatically replace samples and SPE columns, without manual operation in the middle, and fully meet the requirements of automation. 4. No reagents are directly exposed to the laboratory environment to avoid laboratory environmental pollution; the sample position and collection position will not move out of the host when the entire method sequence is running, to avoid collisions, and no additional space is required. 5. Using the column inserting rod technology, the column inserting rod is close to the top of the SPE column packing, and the set liquid flow rate is the flow rate of the liquid flowing through the SPE column to ensure the parallelism of the recovery rate. 6. It is quicker and more convenient to replace different types of post rods without tools such as wrenches. 7. Column inserting rod cleaning, needle cleaning and active drainage, the injection needle has the function of cleaning the inner and outer walls 8. The host has a large touch screen, no external computer control is required, and the operation is simple and easy to understand. It can directly edit the setting method and transfer method of the prescription, and has the intelligent reminder function of method editing error technical parameter: Sample processing capacity: 24 samples in batch (2*12), applicable to 1ml/3ml/6ml/12ml/20ml SPE column, multi-sample column loading Sampling mode: independent mode of column plunger and suction needle Optional solvent number: 8 kinds (12-port valve) SPE column type: suitable for 1ml/3ml/6ml/12ml ordinary SPE column Column change method: Quick column change, switchable 1ml/3ml/6ml/12ml column insert Collection tube volume: 20ml, 80ml glass tube optional Column insertion rod cleaning: Yes, optional String column function: use short column for string column Waste discharge channel and method: 3 waste discharge channels, peristaltic pump actively discharges waste Injection needle cleaning: It has the function of cleaning the inner and outer walls, and the outer wall is purchased and soaked Sample loading accuracy: 10ml sample accuracy is 1% Bottle bottom washing function: Yes, the bottom washing function of the sample bottle Sample tube volume: 20ml, 80ml glass tube standard Number of sample racks: 24 for 15, 20ml, 12 for 80ml Large-volume sample loading: Optional 24-bit large-volume sample injection module Instrument tightness: Purchasing a sealed design, volatile solvents are discharged from the exhaust port Waste liquid separation: Waste liquid flow path: wastewater and two organic solvents respectively Column drying method: Dry the SPE column with nitrogen Air pressure: Air pressure input: maximum 100psi air pressure output: 0-20psi Materials in contact with solvents: stainless steel 316L, PPS, Teflon and PEEK materials Indicator light: 3-digit indicator Operating system: wireless control/large touch screen Pause button: Yes, it can be stopped at any time during work
