Features:

  • Easier operation with a large display screen
With 9 operation keys and a large 40 characters x 8 row display screen, it is easier than ever to input programming and parameter settings. The graph display of chromatography signals makes it easy to determine the status of fraction collection.
  • Reliable construction
The water-sensitive operation panel as well as the mechanical and electronic parts are placed behind the test tube rack to protect against water droplets for a practical, long-lasting design.
  • Supports different sized collection vessels
The vertical dial allows 70mm of movement to adjust the dropper nozzle position to the test tube length (105 ~ 180mm). The standard test tube rack will hold 120 tubes with a diameter of 12 ~15mm (maximum of 18.1mm with
the standard rack holder removed). Large volume vessels can be set when the rack lid is removed.
  • Quick nozzle movement with higher resolution
A sturdy frame and higher resolution stepping motor are used. The nozzle moves accurately to the set position, from tube to tube in 0.1 seconds.
  • Unneeded constituents drained
Waste constituents are drained out so test tubes are not unnecessarily
contaminated.
  • Safe, chemically resistant material
The exterior of the unit is made of flame retardant ABS plastic, and the test tube rack and drain are made of chemically resistant polypropylene.

Loaded with Unique Collection Functions

Simple mode: Collect by time, drops, volume or signal.
Manual mode:
Collect fractions while watching the chromatography signals displayed on the screen. A fraction may be reviewed under playback mode.
Peak Mode: Specify up to a maximum of 10 peaks for identification. Peak determination maybe made using a combination of absolute value and slope angle.
Example of peak absolute value setting
Set the percent value using an input signal full scale of 100%. Peaks above the set absolute value are identified.
Example of slope angle setting
As shown in the graph at right, because of baseline drift, only three peaks are identified at 1,2/3 and 4/5/6/7/8 by absolute value setting. However, by using a slope setting, all 8 peaks are identified.

Window mode

A maximum of 16 windows (time ranges) may be set so that peaks are identified and fraction collection occurs only within each window. By setting the monitor
time, non-peaks may also be collected in the test tubes.
Window mode setting, example 1
Window 1 is set between 2min00sec and 2min32sec at request time of 12sec. Window 2 is set between 3min32sec and 5min00sec at 8 sec request time.
  • Main settings: Wait time: [40 sec]
    Non-window monitor time: [0 sec]
  • Window settings:
    01: Start [2min00sec] ~ End [2min32sec]
    Request time [12 sec]
    02: Start [3min32sec] ~ End [5min00sec]
    Request time [8 sec]
  • Peak parameters:  Absolute value: [0%],
    Slope angle: [0mv/min]
    Response: [*HIGH], Delay time: [0 sec]
Window mode setting, example 2 (peak identification)
Window mode setting, example 2 (peak identification)
Peaks within the windows are identified. Fraction collection is set at 12 seconds during peaks for window 1. For non-peaks, the monitor time interval is 8 seconds.
  • Main settings: Wait time: [40 sec]
    Non-window monitor time: [0 sec]
  • Window settings:
    01: Start [2min00sec] ~ End [2min32sec]
    Request time [12 sec]
    Monitor [08 sec]
    02: Start [3min32sec] ~ End [5min00sec]
    Request time [8 sec]
    Monitor [24 sec]
  • Peak parameters: Absolute value: [40%]
    Slope angle: [20mV/min]
    Response: [*HIGH], Delay time: [0 sec]
Sampling mode
Collect fractions for a set interval during a set period. Multiple collections may be set per test tube. In the setting example shown on the right, wait time is 5 minutes, each test tube has 2 repeats of 5 minutes intervals every 15 minutes.

Setting Example = Sampling Mode
Multiple sample functions
After a fraction collection has completed, the next fraction sampling begins at the next test tube or after skipping one tube
Synchronize the chromatogram and collection
using the time delay function
Because of the distance from the UV absorption detector, refractometer or other instruments to the fraction collector dispense nozzle, there is a delay from the point of graphing until the sample
is collected in the tube. By inputting the lag time,
the collected sample can be set to accurately conform to the record (chromatogram).
Verify the fraction collection results by looking at the graph
The results of up to 500 events can be displayed.
Chromatography signals are displayed in peak, window and manual modes.

Fraction result display

Peak signal graph display
Operate using a computer
Using a computer , the parameter settings for each mode as well as starting, ending, pausing and advancing can be controlled. By loading up to 500 fraction results into the computer, the operation history of the equipment and test results can be easily verified
Sample liquid chromatography system set-up
After inserting the sample into the top of the column, the elute separates out. While characteristics are measured with detectors,  the separated substances are eluted into the fraction collectors
Example of sampling system set-up
A small amount is sampled at a fixed interval, and inserted into the fraction
collectors
