Fully Automatic Secondary Thermal Desorption Instrument

Fully Automatic Secondary Thermal Desorption Instrument

  • Product Number:LD-HA3
  • Product Difference:30 sample positions accommodate large sample volumes, analyze chemical composition, and evaluate thermal resistance

Product Introduction

The fully automated secondary thermal desorption instrument delivers outstanding performance in both operational capabilities and differential thermal analysis. It enables high-precision weight measurement with a broad monitoring range, capable of analyzing extremely small samples. Additionally, this instrument facilitates comparative analysis between samples and reference standards to obtain information on the chemical composition of samples. For thermal stability testing, it measures sample mass changes and weight loss rates relative to temperature variations, thereby evaluating the thermal resistance of samples.

Product Features

  • 10-inch color touchscreen with comprehensive, intuitive parameters for online monitoring.

  • Power-on self-test, gas pressure differential alerts, automatic positioning, and sample tray calibration.

  • Full load capacity of 30 sample positions to accommodate large sample volumes.

  • Program-controlled sample tray tube positions enable targeted tube detection.

  • Microcomputer program control allows method parameter settings with real-time animated display of operational status and runtime.

  • Four independently heated zones: desorption chamber, injection valve, sample transfer line, and secondary desorption chamber.

  • Fully automated low-temperature secondary desorption using semiconductor cooling.

  • All gas lines passivated.

  • Automatically executes primary desorption, secondary desorption, and backflush cleaning based on method parameters.

  • Synchronizes startup with GC and chromatographic data processing workstations for rapid analysis initiation.
