Chromatography 37 Collaboration to Measure Atmospheric Pollution Announced
Chromatotec recently welcomed a research team from the PRAT (Atmospheric Reactivity Platform) to its laboratories after partnering with them on air pollution control and measurement solutions. Managed by the CNRS and University of Orleans, the PRAT studies the impact of gaseous and particulate pollutants emitted by human activity (transport, pesticides, heating, industrial activities) on health, climate and the environment. Chromatotec collaborates with the ICARE-CNRS Laboratory through analytical development of GC-MS techniques for atmospheric measurement of volatile and semi-volatile organic compounds. The two entities will combine their expertise to validate the analytical system performance.

New Chilling/ Heating HPLC Column Temperature Controller Announced
Torrey Pines Scientifi c, Inc announces its new EchoTherm™ Model CO50 Programmable HPLC Column Chiller/Heater.
The unit has a temperature range from 4.0°C to 100.0°C readable and settable to 0.1°C. The PID control software regulates temperatures to ±0.2°C, even at ambient. The CO50 has a Stable Temperature LED that illuminates when the target temperature is stable to within ±0.2°C.
The Peltier-based CO50 has 5-program memory of 10 steps per program and the ability to repeat any program from 1 to 99 times automatically. It is ideal for chiral and biomedical chromatography where below ambient temperatures help preserve bioactivity. It can be used for stabilising column temperatures from day to day at or near room temperatures for repeatable results. The CO50 holds columns up to 30cm long by ¼” or 3/8” diameter in mounting clips provided. Larger diameter columns can be used by removing the column clips that hold the smaller columns.
The CO50 features RS232 I/O port for controlling the unit by a chromatograph, for programming gradients, and for data collection. Also included are an injection counter, 30-day timer with user settable Auto-Off, and chamber drain for spills.

Unique HPLC Columns for Extremely Polar Samples
Cogent Diamond Hydride™ HPLC Columns from Microsolv have a silica-hydride surface similar to other Cogent TYPE-C™ phases, but the uniqueness of Diamond Hydride™ is that they have a very small amount of carbon on the surface that adjusts the hydrophobicity to an important level.
It has been the choice of scientists working in metabolomics, bio-analytical or with LCMS for compounds such as amino acids, organic acids, carbohydrates, and very polar small molecules. Non-polar and polar peptides have been separated in the same run.
An important alternative to HILIC, these columns perform extremely well in Aqueous Normal Phase which uses Acetonitrile and Water but equilibrates very rapidly and the data produced is very precise.
Available in Guard, Analytical or Prep sizes with 100A, 4um or 2.2um particle sizes. More information online:
