SerCon-GSL Sample Preparation Unit

• High quality stainless steel diaphragm regulators for gas contol, digital flow and pressure sensors, normally closed valves save gas and preserve consumables on power failure.

• Two long-life furnaces capable of operating to 1100°C i.e. both furnaces can be used for pyrolysis, combustion or reduction applications.

• On-board microprocessor for storage of furnace temperatures and valve status (guards against PC failiure or temporary detachment).

• Total software control of the instrument system and data processing.

• Original dual isotope analysis of ¹⁵N and ¹³C in a single sample developed by Europa Scientific. Proprietary GC column to achieve baseline separation of N₂ and CO₂ which is essential for this mode of analysis.

• Software controlled oxygen injection to match sample requirements thereby preserving the life of the consumables.

• Re-chargeable water and carbon dioxide chemical traps. CO₂ trap is switched in/out of line by software to avoid leaks on changing analytical mode.

• Gas sampling from septum sealed containers by the original continuous flow flushing method. Purge facility on needle to prevent sample carryover. Full automation via a software controlled autosampler that can accomodate 200 x 12 ml septum sealed containers (optional bar code reader).
