JAS Double Chamber CryoTrap
JAS double chamber CryoTrap is a powerful and high-quality trap that combines the latest advances in CryoTrap technology like low thermal mass, efficient insulation and maximum heating power to efficiently trap volatile compounds in the front part of a capillary column.
Flexible: To meet analytical needs JAS CryoTrap can be installed at various positions (two locations inside the GC oven and one location outside).
3 cooling options: liquid CO2, liquid N2 and pressurized air
Efficient: By means of a double chamber design the JAS CryoTrap features effective insulation reducing the coolant consumption to a minimum.
Easy to Use: Dedicated and optimized alignment of tuning parameters provides excellent performance at any oven temperature
Economical: JAS CryoTrap is controlled either by Agilent ChemStation software or by GC keyboard. The use of the Trap is easy and can be embedded into every GC method.
The JAS CryoTrap allows to trap (very) volatile components and preconcentrate components before being injected on a gas chromatograph separation column. This refocusing step results in a narrow band injection and overcomes peak broadening issues and related separation problems. It will improve integration- and peak identification of the various peaks in the chromatogram.
The JAS CryoTrap is specially designed for installation in an Agilent 7890 or 6890 GC. This system includes the latest economical- and technical design like a low thermal mass, highly effective insulation, and extreme fast heating rate. These functional properties will ensure reliable operation at any chosen column oven temperature. The extreme fast heating of the cold trap (up to 700 °C/min) enables in a fast vaporization of the trapped components and a better chromatographic separation.
The possibility to choose various coolants adds high flexibility to the JAS CryoTrap and guarantees optimal analytical performance:
- Cooling by means of liquefied N2 (-160 °C)
- Cooling by means of liquefied CO2 (-60 °C)
- Cooling by means of dried instrument air (starting from ambient- or initial temperature of the column oven)
The CryoTrap in detail
The JAS CryoTrap includes a double chamber design, with a Stainless-Steel housing. The inner chamber is made of a special material with optimal heat conductivity properties.
The double chamber design ensures optimal insulation of the CryoTrap at minimal coolant consumption.
The JAS CryoTrap is installed at the left-hand side of the column oven wall in an Agilent 7890 or 6890 GC. The (capillary-) analytical column is guided through the JAS CryoTrap and then connected to the inlet. By means of the chosen coolant the inside of the JAS CryoTrap is cooled down to the pre-set temperature. The part of the capillary column inside the JAS CryoTrap is then cooled down too and acts as a cold trap, where the components are temporary frozen before elution and separation on the analytical column. The extremely fast heating rate allows you to evaporate and transfer the frozen components in a narrow band onto the column. Temperature- and time settings are depending on the application and components of interest. These settings can be controlled and optimized by means of the OpenLab Software.
