Utility Model No. 201 07 702.7 (German Patent and Trademark Office). The SIM injector is a new type of split/splitless injector for the GC systems Agilent 8890 /7890 / 6890 / 6850 / 5890: The gas lines for the carrier gas and the septum flushing are now in the injector instead of the usual upper part -Bottom.

This supplement for the Agilent detectors MSD 5975 and 5977, Triple Quadrupole Mass Spectrometer 7000/7000D/7010B, as well as the 7200 GC-Q-TOF enables the direct acquisition of mass spectra without uncoupling the GC/MS interface. Additionally we offer the Direct Inlet Probe system also for GC/MS systems by Shimadzu and Leco. A push rod is used to insert the sample into the vacuum of the ion source to record the mass spectrum:

The SIM high-temperature (HT) injector is designed for long-term operation at a maximum end temperature (up to 450°C ). This all- metal version of the SIM injector is therefore particularly suitable for H53 and SIMDIS methods (e.g. EN ISO 3924 , ASTM D2887/D6352 ).

The Precision Series Zero Air Generators are specifically designed to produce clean, dry, and hydrocarbon-free air. The air is provided for use as a fuel gas in the GC and, with FID detectors, provides an absolutely flat baseline with almost no noise floor. This quality is the prerequisite for good analysis results in the trace range. The zero air has a hydrocarbon content of < 0.05 ppm (measured as methane) and thus corresponds to the quality of UHP bottled gas. If there is no supply of compressed air, this can be generated with the Precision Air Compressor.
