液固相漫反射原位池

PX-RC-DRS-A3

液固/气液固 · 低死体积 · 瞬态光谱

产品介绍

适配各主流品牌傅里叶变换红外光谱仪和紫外-可见吸收光谱仪。配备拉曼穹顶，还可用于拉曼光谱原位表征。研究对象为气液固相或液固相体系。可在常温至高温、真空至高压范围内工作（最高温度与最高压力不可同时达到，详见参数表）。其极低的内部无效体积确保了气体的平均停留时间低于2秒，是光谱动力学研究的理想选择。

Liquid-Solid Diffuse Reflectance In-Situ Cell

PX-RC-DRS-A3

PRODUCT INTRO

Compatible with mainstream FTIR and UV-Vis spectrometers and equipped with a Raman dome for in-situ Raman characterization, the PX-RC-DRS-A3 is designed for gas-liquid-solid and liquid-solid systems. It covers vacuum-to-high-pressure and ambient-to-high-temperature conditions with an extremely low dead volume that keeps average gas residence time below 2 seconds, ideal for spectroscopic kinetics research.

PRODUCT ADVANTAGES

Supports liquid-solid and gas-liquid-solid systems
Low dead volume — suitable for transient spectroscopies such as SSITKA and MES
Inlet gas is preheated by the integrated heating stage, preventing cold gas from directly contacting the catalyst
Thermocouple inserted directly into the catalyst bed, giving readings closer to the true reaction temperature

PRODUCT SPECIFICATIONS

Temperature Range	Ambient–850 °C; accuracy ±0.2 °C
Pressure Range	Vacuum–4.0 MPa *
Body Material	Heating stage: 310S stainless steel; housing: 316 stainless steel (built-in water-cooling channel)
Window Material	IR: Quartz + ZnSe; UV-Vis / Raman: Quartz
Temperature Sensing	K-type thermocouple, tip placed directly inside the catalyst bed
Heating Method	Twin heating rods in symmetric arrangement, 20 V/300 W per rod (600 W total)

NOTE

* Maximum temperature and maximum pressure cannot be reached simultaneously; reduce the working pressure accordingly at elevated temperature.
