SEDEX LT-ELSD 90LT     For HPLC and U-HPLC

 

sedex_90-upload-s90-320-75.pngSEDEX LT-ELSD 90LT 는 Sedere 사 고유의 이동상 용매를 낮은 온도에서 증기화 시키는 


Low Temperature (LT) 기술이 적용된 HPLC, U-HPLC 전용 저온 증기화 광산란 검출기 입니다. 

 

 

LT-ELSD는 발색단(chromophore) 및 광학적 특성에 의존하지 않으며,


이동상보다 덜 휘발성인 모든 화합물 검출에 사용 됩니다.

Low-Temperature detection


The unique design of SEDEX LT-ELSD Nebulization cell allows the selection of the droplets as a function of the size. Large droplets, which are more difficult to evaporate, are responsible for an increased noise level. In the glass nebulization cell, the largest droplets are simply discarded, so that the temperature can be lowered, without compromising the sensitivity (signal to noise ratio):

This diagram illustrates the selection of the droplets as a function of the size. The mist of droplets is created by the nebulizer, and is composed of droplets of various sizes. The nebulization cell acts as a real Size Exclusion Selector, so that the droplets of largest dimension (in blue on Figure) are evacuated to the waste. Only droplets which are below a size limit are allowed to flow through the drift tube.

 

Most of our competitors’ ELSDs do not select droplets and require higher temperatures to reach acceptable levels of noise during the analysis, resulting in much lower sensitivities for semi-volatile and thermo-labile compounds.

 

Selection of the droplets is a unique feature of SEDEX LT-ELSD and provides the real Low-Temperature evaporation, and the best sensitivity for all compounds.
