FAQ
【MJT】Can I use the Micro-Jet Cryo-Trap as a stand-alone re-concentrator?
Yes, the MJT-1035E can be used in a stand-alone configuration – no Pyrolyzer is needed. In this case, the Cryo-trap is manually operated; however, it can be automated using control devices and or software from a third party.
【MJT】How much liquid nitrogen does it consume?
It consumes 20 mL/min when it cools to -190 ºC and 15 mL/min in operating at -150 ºC. The standard Dewar containing 2 litters of liquid nitrogen lasts for about an hour.
【MJT】What type of container do you recommend for liquid nitrogen?
A 2 litter Dewar is provided. Commercially available 10 or 30 litter liquid nitrogen Dewar can be used, but it will be necessary to replace the heat exchanger to accommodate the larger Dewar. Call your local distributor for details or contact us.
【MJT】What is the rate of nitrogen gas consumption?
When it is cooling to -190 ºC (butane can be trapped), 7 L/min of nitrogen is consumed. When cooling at -150 ºC (hexane can be trapped), 5 L/min is consumed.
【MJT】When it is not used, is it all right to leave the thermal exchange coil immersed in liquid nitrogen?
Even when it is not in use, it consumes limited amount of liquid nitrogen. When it is not in use for a short period of time, there is no problem to leave the thermal exchange coil immersed in liquid nitrogen; however, be sure to leave the nitrogen supply and the Cryo-trap stopcocks open so that nitrogen gas can flow. Failure to do so can clog the thermal exchange coil by frozen moisture in air.
When it is not used for a long period of time, take the thermal exchange coil out of the liquid nitrogen.【FS】Can libraries compiled by Frontier Lab be searched with data generated on a GC/MS of any manufacturer?
The F-Search (PY-1110E) software is totally independent from the GC/MS analysis software offered by GC/MS manufacturers. F-Search is compatible with NetCDF MS data format used by all GC/MS systems manufactured by Agilent (MassHunter and ChemStation), JEOL (Q1500, Auto MASS, and K9), and Shimadzu. For NetCDF (AIA) conversion software, contact the manufacturer of your GC/MS.
【FS】What is the minimum configuration requirement for the PC?
A PC running either Windows 11, 10, or 8.1 of 64/32 bit operating system for all languages.
【FS】Is there a trial version available?
30 day trial version of F-Search version 3.4 is available and can be downloaded from our website.
【FS】Can I use libraries of old versions with the latest search software?
Yes, when the new search software starts up, libraries of old versions will be automatically converted to ones with newer format.
【FS】How can I check the version number of the library that I am using?
The version number of library can be found in the filename of the library that starts with “MS”. The numeric and character follow “MS”. The larger number indicates a newer version. Character “B” is newer than “A”. The filename can be displayed by selecting from menu bar: “Library” – “Select Library for Search”.
