Sample Pretreating

Laboratory sample pre-treatment, also known as sample cleaning or sample preparation, are critical for ensuring that the sample is in an appropriate form for measurement, removing potential interfereneces, and improving the accuracy and reliability of the analysis.

In analytical chemistry, sample pre-treatment can involve several instruments such as Solid-Phase Extraction, Ultra-pure Water Purifier, Stirrer, Mixer and Homogenizer, Filtration and Centrifuge, Digestion, Rotary Evaporator, and Nitrogen Evaporator, depending on the nature of the sample and the analytical technique to be used.

Solid Phase Extraction System

Solid Phase Extraction(SPE) Systems are advanced instruments developed by integrating liquid-solid extraction and liquid chromatography technologies. They utilize solid adsorbents to adsorb target compounds from liquid samples, separating them from matrix and interfering compounds. Target compounds are then eluted with eluents or desorbed by heating, achieving the purposes of separation, purification, and enrichment. These processes reduce matrix interference and enhance detection sensitivity. The systems are applied in food safety testing, agricultural residue monitoring, pharmaceutical & healthcare, environmental protection, commodity inspection, tap water analysis, and chemical production laboratories.

Semi-automatic Solid-phase Extraction System

The split-type semi-automatic SPE system is specifically engineered for laboratories requiring efficient and precise sample pretreatment. Characterized by advanced design and reliable performance, it is equipped with a high-precision peristaltic pump that enables accurate control of column flow rate. By digitizing the complex "column flow" process, it ensures highly reproducible solid-phase extraction results. Users simply add samples and solvents to the reservoir, then initiate the process with a single tap on the touchscreen, allowing for effortless completion of all key SPE steps. This user-friendly design effectively minimizes experimental errors and consistently delivers high-quality samples for subsequent analytical testing, making it an invaluable tool for both routine laboratory operations and advanced scientific research projects.
