Fraction Collector

Introduction

A fraction collector collects separated fractions in chromatography processes. It is widely used in biochemical and chemical laboratories. The system ensures sample integrity. It solves manual collection errors. By providing automated fractioning, it supports analytical workflows.

Features

Offers a range of high-performance Fraction Collectors designed for precise and efficient separation of liquid samples in chromatography and analytical workflows. These instruments support collection based on time, volume, or signal, ensuring reliable operation for routine or specialized lab processes. They features compact design, user-friendly programming, multiple collection modes, and compatibility with various column systems and vessel types. Collectors are ideal for use in pharmaceutical, research, and chemical laboratories.

FAQs

1. What is a Fraction Collector and why is it used in laboratories?

A Fraction Collector is used to automatically collect liquid samples (fractions) coming from a chromatography column. It enables researchers to separate complex mixtures into individual components by collecting them in a time-based, drop-based, or signal-based sequence. It is essential in biochemical, pharmaceutical, and analytical labs for reproducible sample collection and purification.

2. How does a Fraction Collector work in chromatography applications?

Fraction Collector is an important tool in various chromatography applications as during a chromatography run, the output from the column is directed to a fraction collector. The collector receives signals (such as time intervals, drop counts, or peak detection data) and moves the test tube tray or collection arm to deposit each fraction in a designated tube. This allows precise collection of separated compounds without manual intervention.

3. Can Fraction Collectors be integrated with detectors or chromatography systems?

Yes, most of the Fraction Collectors can be triggered externally via signals from detectors (UV, RI, conductivity) or chromatography software. This allows automated and accurate peak-based collection, ideal for separating closely eluting compounds or monitoring real-time sample outputs.

4. How does solvent compatibility affect the operation of a Fraction Collector?

Solvent compatibility is critical, especially in chromatographic separations involving organic solvents, acids, or buffer solutions. A Fraction Collector must be constructed from chemical-resistant materials (e.g., PTFE, ABS, stainless steel) to ensure long-term durability and prevent damage or contamination.
