顶空进样器 (CAS No.None)
- 物化性质
- 基于气-液（气-固）平衡原理，将待测样品置于密闭容器中加热升温，使挥发性组分从样品基体中挥发出来，在气液或气固两相中达到平衡后，直接抽取顶部气体进行色谱分析。该技术可免除冗长繁琐的样品处理过程，避免有机溶剂对分析造成的干扰，减少对色谱柱及进样口的污染。
- 技术参数
- 支持手工进样、气密针进样、平衡式加压、定量环加压、静态-动态补偿式五种进样方式。 可与国内外各种型号气相色谱仪直接连接，兼容性强。 加热平衡后直接抽取顶部气体进样，避免有机溶剂干扰，减少色谱柱污染。 静态-动态补偿式具备吹扫、恒定、多次顶空及温度渐进模式，提供多种样品提取手段。

Product Name:Headspace Sampler
English Name:Headspace Sampler
Aliases:Static Headspace Sampler, Headspace Autosampler for GC
Physical Properties:Based on the gas-liquid (or gas-solid) equilibrium principle, the sample is placed in a closed container and heated so that volatile components are released from the sample matrix. After reaching equilibrium between the gas and liquid (or solid) phases, the headspace gas is directly extracted for chromatographic analysis. This technique eliminates laborious sample preparation steps, avoids interference from organic solvents, and reduces contamination of the chromatographic column and injection port.
Uses:Used for qualitative and quantitative analysis of volatile components in gas chromatography, suitable for sample pretreatment in food, environmental, pharmaceutical, and chemical industries. It can be connected to various domestic and international gas chromatographs, enabling users to obtain abundant useful information within a short time.
Technical Specifications:
Supports five injection modes: manual injection, gas-tight syringe injection, balanced-pressure system, pressure-loop system, and static-dynamic compensation system.
Directly compatible with various domestic and international gas chromatographs.
Direct headspace gas injection after heating equilibrium, avoiding organic solvent interference and reducing column contamination.
Static-dynamic compensation mode offers purge, constant, multiple headspace, and temperature-programmed extraction modes for versatile sample handling.
