Fraction Collectors

Why fraction collectors

After separating or purifying the target compounds the eluent with the ompound fractions will leaves the column either to the a detector  or directly to the fraction collector.

There are many different models of fraction collectors, small once, large ones, round ones and large once – it all depends what you aim to achive.  Most users of fraction collectors do that to harvest the separated and purified compounds for

  1. Further Analysis
  2. Sale of purified compound
  3. Clinical evaluation
  4. Further syntheitic modification

What kind of Fraction Collector fits your requirement?

 There are a wide range of different Fraction Collectors available  ranging from Integrated square box types for mainstream analytical HPLC systems to Rotary FC to XY Cartesian FC and Prep and Production Scale Fraction Collectors with and without EX Protection.  Most people require special performance parameters and have some ideas how much they are ready to pay. We offer a standart range, adoption of standart rang to meet special requirements or   custom design and construction.  Our Range comprises :

Consensus Rotary Fraction Collector FC 80

Description

The compact Rotary fraction collector represents an easy to use and competitive alternative. It is a reliable partner for basic systems.
It has and inbuilt timing system to dial 1 to 99 sec or 1 to 99 minutes fraction collection for each collection vessel. For more complex, computer or detector controlled systems  an impulse cable is available to trigger a signal  via TTL or potential-free contacts.
Optionally we can supply  waste/fraction valve to dispose eluents into a larger storage tank. Additionally the valve is operated during every change. A marker indicates the fraction change in the chromatogram. The spring supported arm automatically changes from one to the next the row. Manual interaction is not necessary anymore.

Consensus Spider Fraction Collector

Description
Spider Fraction Collector is a solenoid valve system that can be controlled through an external PC with 32 bit Window system and appropriate Driver program, – manually through the PC keyboard or automatically through a PC program. Spider allows automation of flash or preparative chromatography fraction collection process
An input three-way solenoid valve is connected before pump.
Solvent supply through the valve to the pump is through valve B. For sample injection use valve A that is switched on for a programmed time. Valve C is used for column washing.
An output six-way solenoid valve is connected to the detector output. Wanted fractions are collected by switching on/of various positions of the output six – way valve.
At the back panel connector are pins that can be switched on by the program ECOMAC. They can be used for control of next units, for example, for external valve switch on when column is washed.
Fraction selection is either by
1. Time table control
2. By peak detection from a peak detectors signal

Consensus Fraction Collector XY-FC160

Description
This compact Fraction Collector XY-FC 160 posses various possibilities to collect fractions. Besides impulse- and time-controlled fraction collection one can gather the flow quantity of the pump and thus collect an adjustable volume per fraction. This Fraction Collector can also be used in parallel chromatography to collect fractions in up to 10 channels at the same time.
Customer-specific tanks can be integrated by simply adjusting the rack parameters.
With the optionally available waste/fraction valve unused solvents can be disposed in a larger storage tank.
Additionally the valve is operated during each glass change. A marker indicates the fraction change in the chromatogram.

Technical specification
Compact XY-fraction collector wit optional Z-axis
2 standard racks for testing tubes
1.for 16mm tubes (160 tubes)
2.for 30mm tubes ( 80 tubes)
1 programmable rack
