Kromasil anniversary 30 years of chromatography
Beyond expectations
30 years has gone since Kromasil was first introduced to the market and changed the performance expectations on preparative HPLC packing materials.
Today, Kromasil is offering a full range product line for analysis and production by UHPLC/HPLC and SFC and stands ready to support your future separations.

for a Quiet Lab Laboratories are often noisy due to vacuum pumps, water chillers, ultrasonic cleaners, nitrogen generators and other instrumentation. Noise makes working conditions around equipment uncomfortable and tiring. An MS Noise Acoustic Enclosure provides the solution you need.
Ionbench’s wide range of boxes can accommodate most vacuum
pumps and water chillers. All noise enclosures are equipped with acoustic foam for a -15dB(A) noise reduction (average 75% down in perception). They are also equipped with fans for a perfect heat exchange and with an over-temperature buzzer alarm with battery backup so as to protect the device from over-heating.
Installation is very easy and neither tool nor vacuum breakage is required. Some models have a side window to check oil levels and a side trap door for an easy access. A stainless steel tray on four vibration absorbing castor wheels can also be available to easily drain oil leakage and move the pump and box in the lab for maintenance.

Comprehensive two-dimensional gas chromatography (GC×GC) is a very powerful separation technique in which the carrier gas eluting from a capillary GC column (first dimension) is introduced onto a second capillary column (second dimension) with different but complementary separation mechanism. This way the sample is subject to two different separation processes within a single analysis. This increases remarkably the peak capacity and leads to an enormous resolving power. Compared to a single
column separation, GC×GC can provide highly detailed sample characterisation and excellent visualisation of sample components.
This device continuously fractionates the eluate of the first column into slices and re-inject them into the second dimension, where further separation occurs. Typically eluting peaks from the first dimension are cut by the modulator into 3-5 slices. The separation on the second dimension column is very fast, typically 3-8 seconds.
There is no ideal modulator that is the best choice for all applications. Selecting the right modulator is of critical importance because it can affect dramatically the quality of the GC×GC results and the user-friendliness of the set-up. This choice should be tailored on your need, see what possibilities JSB offer.
