General Information:

Split/Splitless Capillary

• Range to 400 °C in 1 °C increments
• Back-pressure design permits independent adjustment of split flow rate without affecting column flow
• Septum purge built in at 3 ml/min
• Accepts columns up to 1.2-mm od
• Multimode design includes split and splitless injection
• Splitless purge time variable in 0.01-min elements
  

Flame Ionization Detector

• Range to 450 °C
• Grounded jet and current limited design for operator safety
• Push-button flame ignition
• Sensitive:
