Column cartridge

Column cartridges include heated detector/injector zone and a column in an oven with temperature programming. Standard available column types are PDMS, MS5A, QS-BND, U-BND.

Sampling

• Sample conditions: non- condensing gas of 0°C to 50°C
• Sample inlet: 1.6 mm (1/16”) stainless steel Valco fitting with replaceable 5 µm stainless steel filter
• Max sample inlet pressure: 300 kPa (44.1 psig) conditional to sample pressure not exceeding column operating pressure

• 2-Stream selector (double block and bleed)
• Sample vacuum pump

Integrated Sample injector and detector

MEMS based injector and detector are on-chip integrated (avoiding capillary tubes), with direct column coupling.

Sample injector:

• Heated injector up to 150°C
• MEMS based injector without moving parts.
• Injection volume: 0.2 µL to 7.5 µL, software selectable

Detector:

• Dual-channel MEMS micro Thermal Conductivity Detector (TCD)
• Internal flow path: 20 nL
• Inert coated filaments

• WCOT columns: 1 ppm
• Micro-packed columns: 3 ppm
  This will vary by compound, sample matrix injector type, carrier gas and interferences.

• Concentrations: 1 ppm to 100%
• Linear dynamic range: 106
  

Repeatability

< 0.5% RSD for WCOT columns for C1-C6 components at % level

Column temperature control

2 modes: T-programmable or isothermal

• Ambient plus 15°C to 180°C
  
• T-ramp up: 240°C per minute
• T-ramp down: 60°C per minute
• Temperature repeatability: = 0.1°C
• T-programming profile: up to 10 segments
  

• Ambient plus 15°C to 180°C
  
• Temperature stability: < 0.1°C

• All four major carrier gasses helium, hydrogen, nitrogen and argon
• Instrument inlet: 500 ±10 kPa (72.5 ± 1.5 psig)
• Column pressure control 50 – 300 kPa, user selectable
• Carrier inlet: 1.6 mm (1/16”) stainless steel Valco fitting with replaceable 5 µm stainless steel filter
