The TriPlus RSH sample handling platform brings together a number of technological innovations that further expand autosampler productivity, performance, and versatility for GC and GC/MS applications. In particular, the system’s automated, high-precision sample handling eliminates the manual labor and downtime traditionally required for tasks such as standard or stock sample dilutions or internal standard addition and derivatization. 

Automatic Syringe Changeout 

• Automatic Tool Change (ATC) capability automates the exchange of syringes for different tasks in a single, unattended sequence. * Automatic switching of syringes for different analytical tasks ensures zero carryover. 

  Unprecedented Sample Capacity * Expand unattended operations and productivity * Capacity for 972 2mL sample vials combined with multiple 100mL wash/waste bottles allow for weekend-long unattended operation 

  Vial Bottom Sensing Expands Application Range * Precisely detecting vial bottom enables the autosampler to accurately withdraw microliters or fractions of microliters from sample amounts in as little as 5µL. * Autosampler enhances productivity and quality of results for sample-limited applications; e.g., trace analysis, radioactive samples, and samples requiring expensive internal standards. 

  Flexible Liquid Sampling and Injection * Optimized liquid injection modes support a wide range of sample types, inlets, and techniques for syringe filling—including Regular Mode, Fast Mode (injects in less than 100ms), and Sandwich Mode. * For highest precision sampling, all parameters can be programmed—including pull-up strokes, viscosity delay, washing cycles, and needle depths. 

  Automated Headspace Injection for Volatile Analysis * High temperature-resistant, gas-tight syringe eliminates the need for a transfer line and/or sample loop for direct headspace injection. * Overlapping sample incubation capability allows higher productivity. * Sample vial capacity of 300 10 or 20mL vials facilitates weekend-long unattended operation. * Optional Multiple Headspace Extraction (MHE) Mode enables accurate quantification of volatiles in a solid or samples with interfering matrices. 

  Automated, Solvent-Free SPME * Precise control of all steps—fiber preconditioning, adsorption and desorption, fiber washes—delivers maximum performance for solid phase microextration (SPME) applications. * Fiber conditioning station automatically flushes and heats fibers after the injection to further boost productivity. * Samples can be automatically heated and shaken to reduce analysis times.
