Contadores de partículas líquidas
No início dos anos 60, Leon D. Carver e a sua equipa na HIAC (High Accuracy Products) inventaram a obscurecimento da luz e o termo contagem de partículas nasceu. A HIAC foi a primeira empresa do mundo a usar uma fonte de luz laser para sensores de obscurecimento da luz. Ao longo de 60 anos, a marca HIAC continuou a inovar e é líder de mercado no dimensionamento de partículas em líquidos ou gases. Estes contadores de partículas líquidas da HIAC estão agora a ser usados para monitorizar fluidos hidráulicos, glicóis, solventes de limpeza, combustíveis, lubrificantes, produtos farmacêuticos, gases comprimidos, água e muitos outros. HIAC é o nome de referência na contagem de partículas líquidas para laboratórios e aplicações industriais.
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>.
