Collection Chamber: Capacity 50-1000 ml

Component Specifications

Definition

The collection chamber is a critical component in automated sampling systems designed to receive, temporarily store, and protect material samples from contamination or degradation during the sampling process. It typically features a precisely engineered interior volume with smooth surfaces to prevent material adhesion and ensure complete sample discharge. The chamber maintains sample integrity by providing controlled environmental conditions (temperature, pressure, humidity) when required and interfaces with transfer mechanisms for automated sample routing to analysis stations or storage containers.

Working Principle

The collection chamber operates on the principle of controlled material reception and temporary containment. When activated by the sampling system, it receives a precisely measured quantity of material through an inlet port, isolates the sample from the main process stream, and holds it securely until the transfer mechanism moves it to the next stage. The chamber may incorporate features like purge systems to prevent cross-contamination between samples, heating/cooling elements for temperature-sensitive materials, and sensors to verify sample presence and volume.

Materials

Stainless steel (AISI 316L or 304), PTFE (Teflon), borosilicate glass, or food-grade polymers (HDPE, PP) depending on application requirements. Materials are selected based on chemical compatibility, temperature resistance, cleanability, and regulatory compliance.
