온라인분석기 - Multi-process Online Analyzers Models L510, L540, L550PC & L560

Titration, UV-Vis spectrocopy, Raman spectroscopy, Colorimetry

미국 LAS사 온라인분석기는 연속적인 무인 작동을 위한 샘플링, 분석, 보고 / 알람, 정리 및 자동 교정 기능을 갖춘 “상자 안의 실험실”이라고 생각할 수 있습니다. LAS 디자인은 최소한의 유지 보수만으로 목표가 달성되는 것을 목표로 합니다. 예를 들어, peristaltic pump를 사용하지 않고 펌프 튜브 교체를 필요하지 않습니다! 대부분의 경우, 분기별 PM만 있으면 됩니다.

The L540 MPA Multi-Process Analyzer

The L540 MPA multi-process analyzer automates sampling, analysis, reporting, and (optionally) replenishment multiple streams including measurement of acids, alkali, metals and numerous other ions. The controller uses known and reliable pH, Redox (ORP), ISE and turbidimetric titrations. pH readings are auto calibrated to eliminate problems caused by in-process sensor drift. Spectral UV-Vis and Raman ranges provide analysis of many organic and inorganic constituents. All analyses are checked for repeatability, range, and tread, and, if necessary, are replicated for verification.
Replenishment is initiated only after all user-configured checks are passed, including volume limits and/or operator approval.

L540MPA: Base model with one titration cell; pH, Pt, and reference sensors; microliter range dose pumps; venturi-driven sampling/waste pump; sample selection valves; and sample and reagent detectors.
