Overview
The HGD-10 Graphite Digestion Robot by Jiangsu Wallong-Hsin Machinery Engineering Co., Ltd. is designed for the wet digestion of samples, utilizing a three-dimensional heating method. It automates processes such as acid adding, shaking, temperature control, and volume fixing, making it suitable for analytical instruments like AFS, AAS, and ICP-MS. The system complies with EPA, national, and industry standards.
Machine Functions
The robot comprises several systems: reagent selection and addition, graphite heating, lifting and shaking, SCARA robot transmission, over-temperature protection, and control and data transmission. It automates reagent addition, sample mixing, temperature control, cooling, and volume fixing. The design emphasizes corrosion resistance, using materials like aluminum alloy, titanium alloy, and PTFE, with Teflon coating for durability against strong acids and alkalis.
Digestion Unit
The unit uses an eccentric shaft rotation for non-contact sample mixing, preventing contamination. It features a 42-position 55mL digestion unit with three-dimensional heating for uniform and rapid digestion. Temperature is PID-controlled, ranging from room temperature to 230℃, with high uniformity. The unit can operate independently or integrate with microwave digestion instruments.
Communication and Software
The robot supports network communication and WiFi, with remote control via a tablet PC. The software offers a graphical interface, customizable digestion steps, unlimited method storage, and remote fault detection. It supports offline operation and seamless LIMS integration.
Liquid Adding Unit
Featuring 6 reagent channels, the unit allows automatic reagent switching and independent control. A high-precision syringe pump ensures accuracy better than 1%. The SCARA robot handles liquid adding, volume fixing, and cleaning, with ultrasonic sensors for precise volume control. The design supports single liquid adding and constant volume operations.
