VISACON VUV-14D 고정파장 자외선흡광 HPLC 검출기

VUV-14D 고정파장 자외선흡광 HPLC 검출기  [Fixed Wavelength Light Absorbance Detector]  Deuterium lamp, 190 nm - 400 nm   Double beam

개 요 VUV-14D 는 크로마토그래피용 고감도 고정파장형 흡광 검출기입니다. 중수소(deuterium, D2) 광원과 190~254nm 파장을 제공하는 협대역 통과필터(narrow band pass filter)의 배열을 이용한 진정한 이중빔(dual beam) 검출기 입니다. VUV-14D 검출기는 표준 HPLC 셀, 5mm 또는 10 mm 투과 길이의 HPLC 셀, 분취용 LC 셀, 캐필러리컬럼을 바로올려 놓을 수 있는 셀 등 다양한 종류의 시료셀(sample cell)을 장착 할 수 있습니다.

특 징 High Sensitivity ; VUV-14D 검출기는 0.0005~4.0 AU/V  감도범위의 고해상도 아나로그 출력신호를 가지며, ±0.00001 이하의 매우 낮은 노이즈 레벨을 나타냅니다. Wavelength Selection ; 중수소(deuterium, D2) 램프는 190nm ~ 400 nm의 파장범위의 광원을 제공하며, 갑섭필터(interference filter)의 사용에 의해 특정파장을 선택할 수 있습니다. Reliable, Rugged, Low Maintenance Design ; VUV-14D 검출기는 신뢰성이 높은 램프와 진정한 이중빔 광원 및 견고한 전원공급장치로 구성되어 있으며, 기기의 피드백 멤브레인 키패드에 의해 제어됩니다.
