Peripherals

Peripherals--aka front ends to the mass specs: Peripherals are listed by manufacturer in alphabetical order. Vendors responsible for updating their own product lines. =**ELEMENTAL ANALYZERS**= =Isoprime Ltd.= The vario MICRO cube is optimised for micro sample analysis and is the universal elemental analyser for IRMS. The vario MICRO cube comes with a 120 position sample carousel as standard. It uses dual furnace technology for separate combustion and reduction steps for better efficiency and shorter down-time. Software controlled, precise oxygen injection provides unique flexibility and ensures highly efficient oxidation of sample. With a single purge & trap separation device the vario MICRO cube has an unrivalled ability to analysing sequential NCS isotopes in under 12 minutes which means that sulphur does not have to be analysed separately as is common with other EAs. For more information about the vario MICRO cube, click here. The vario ISOTOPE cube is the only elemental analyser which has been specifically geared for stable isotope studies and so makes it the ideal choice for most IRMS laboratories. When the vario ISOTOPE cube is coupled to the IsoPrime100 it is the only EA-IRMS system to offer sequential NCHS isotopic analysis from a //**single aliquot of sample**// which is an Elementar //**patented technique**//. This means that multi-elemental isotopic “fingerprinting” of samples is now incredibly efficient since four isotopes can be analysed from a single sample in under 20 minutes. Sequential NCHS analysis improves throughput, sample consumption is reduced and it is simple to do due to the IsoPrime100’s practically limitless dynamic range. An 80 position sample carousel is supplied as standard or a 120 position carousel as an option. For more information about the vario ISOTOPE cube, click here. The vario PYRO cube is the complete solution for all your EA-IRMS needs. The vario PYRO cube is the first elemental analyser to combine traditional low temperature (1200°C) Dumas combustion for NCS with very high temperature (1500°C) thermal conversion for OH isotopic analysis. This means that a single instrument can be used to analyse organic samples for sequential NCS isotopic analysis //**as well as**// the analysis of inorganic samples such as phosphates, nitrates and sulphates for δ18O analysis for the first time. This gives the user unbeatable flexibility whilst saving on cost and valuable bench space. The vario PYRO cube is also capable of analysing OH isotopes sequentially from a single sample/injection.

 * All vario EAs are designed and built to the highest quality which translates to the simplest operation and maintenance for even the most inexperienced of users. The following key components form the core of the vario EAs:
 * Purge & Trap separation of analyte gas mixtures controlled by Thermal Programmed Desorption (TPD) which has been pioneered by Elementar. Purge & Trap separation offers unparalleled multi-elemental “isotopic fingerprinting” performance with guaranteed baseline resolution
 * Absolutely zero-blank ball-valve for sample introduction. Each sample is individually purged before analysis resulting in reliable analysis of extremely low nitrogen concentrations
 * 80 or 120 position sample carousel which can be added to in real-time with no need for stacking, purging or evacuation
 * Vario EAs can be used as standalone elemental analysers with no need for reconfiguration
 * Large range TCD detector which is impervious to oxygen intrusion and capable of detecting elemental concentrations and ratios from p.p.m. to 100%
 * No tools are needed for daily maintenance due to ball and clamp fittings. Ash fingers can be replaced in minutes and furnace tube exchange can be done equally as fast. Active software alerts fore-warn users of impending maintenance requirements
 * Intuitive and intelligent software control which is integrated into IonVantage giving “run-once” sample lists and consolidated elemental and isotopic concentration data in a single report
 * Automated, software controlled leak diagnostics programme makes problem solving simple and fast
 * Easy to configure, optional Vario Liquid Sampler (VLS) for introduction of liquid samples into the EA through a septum-free micro seal injection port.
