HIAC 액체 입자 계수기
액체 입자 계수기(또는 액체 파티클 카운터)는 액체 내에 떠 다니는 입자의 수를 측정하고 세는 데 사용됩니다. 주로 액체 시료 내의 입자 크기 분포를 파악하거나 오염 물질의 측정에 활용됩니다. 벡크만쿨터의 HIAC 입자 계수기로 정확하고 일관성있게 액체내 입자를 모니터링하십시오.
1960년대 초 Leon D. Carver와 HIAC(High Accuracy Products) 팀은 광 차폐법(light obscuration)을 발명했으며 이를 바탕으로 미립자 계수기가 탄생했습니다. HIAC는 세계 최초로 광 차폐법 센서에 레이저 광원을 사용한 최초의 회사입니다. 지난 60년 간 HIAC 브랜드는 혁신을 지속적으로 추구해 왔으며 현재 액체 또는 기체의 입자 크기 측정 시장을 선도하고 있습니다. HIAC 미립자 계수기는 현재 유압 오일, 글리콜, 세정 용제, 연료, 윤활유, 의약품, 압축 가스, 물 및 기타 다양한 액체를 모니터링하는 데 사용됩니다. HIAC은 실험실 및 산업 분야에서 미립자 계수기의 기준이 되는 브랜드입니다.
FAQ on Liquid Particle Counters
What is light obscuration particle counting?
Light obscuration particle counting is a measurement method that uses a laser light source to detect and size particles suspended in a liquid. It is one of the most widely used techniques for pharmaceutical particulate testing and fluid contamination analysis.
How does a liquid particle counter work?
Most liquid particle counters use light obscuration technology. As particles pass through a laser beam, they block a portion of the light. The instrument measures these changes to determine particle size and concentration.
What are USP <788> and European Pharmacopeia 2.9.19 particulate matter tests?
USP <788> and European Pharmacopeia (Ph. Eur.) 2.9.19 are a pharmaceutical standard that define requirements for measuring visible and subvisible particulate matter in injectable drug products These standards establish particle count limits and approved test methods to help ensure product quality and safety. Liquid particle counters are commonly used to perform particle count testing and support regulatory compliance.
What is the difference between liquid and air particle counters?
Liquid particle counters measure particles suspended in fluids, while air particle counters measure airborne particles within a defined volume of air. Both technologies support contamination monitoring but are designed for different sample types and applications.
What is a liquid particle counter?
A liquid particle counter is an analytical instrument used to detect, size, and count particles suspended in liquids. These systems are commonly used in pharmaceutical manufacturing, water testing, and contamination control programs.
What are liquid particle counters used for in pharmaceutical manufacturing?
Liquid particle counters are used to monitor particulate contamination in injectable drugs, biologics, parenteral products, and pharmaceutical process fluids. They help support quality control programs and particulate matter testing requirements such as USP <788>.
