Septum

Description: General-purpose septum Maximum temperature (INJ setting temperature): 250 °C

Description: Using this septum alleviates the problem of reduced durability when the vaporizing chamber is used continuously at 450°C. Compared to the LL septum, the increase in bleed when used at high temperatures is kept at a lower level. The problem of sticking to the vaporizing chamber during continuous use at high temperatures experienced with a conventional septum has also been eliminated. Suitable for high-sensitivity analysis at high temperatures Maximum temperature (INJ setting temperature): 450°C

Description: Provides significant durability improvements compared to a conventional low-bleed septum, offering both low bleed and long life. The problem of sticking to the vaporizing chamber during continuous use at high temperatures experienced with a conventional septum has also been eliminated. Suitable for high-sensitivity analysis Maximum temperature (INJ setting temperature): 450°C

Description: Low-bleed, suitable for high-sensitivity analysis at high temperatures Maximum temperature (INJ setting temperature): 350°C

Description: This septum is least influenced by a plasticizer. Better prevents septum coring. Low-bleed, suitable for high-sensitivity analysis Maximum temperature (INJ setting temperature): 340°C

Description: For HS-10 only To ensure cleanliness and inertness Maximum temperature (INJ setting temperature): 250 °C

Description: Includes: Microseal nut, adapter, O-ring support, 2 size 004 Viton O-rings, 2 Microseals. The Merlin Microseal is a microvalve alternative to the conventional silicone rubber septa used in gas chromatography (GC). The design allows the needle to slide through the sealing elements of the Microseal without piercing or puncturing any material or shedding particles into the liner. This eliminates contamination of the inlet liner with septum particles which produce septum bleed "ghost peaks" and which may adsorb or react with sensitive sample components. Its unique design gives it high pressure capability and resistance to wear which results in long life and excellent chromatographic performance. Operating Requirements: Use only 23 ga (0.63 mm, .025" dia.) cone tip syringe needles or SPME probes. Note that SPME probes are available in both 23 and 24 ga. The 24 ga. probes will not seal reliably with the Microseal. Recommended Operating Conditions: Injection port temperatures: 50 - 450 C. Pressure: 3 - 100 psi (20 - 700 kPa)  

Description: Useful for trace analysis and other applications where high sensitivity is critical Low bleed, highly robust (max. usable temp. 350°C)  High durability, proper sealing and good resistance to most chemical solvents.

Description: The Xtra Life Inlet Septa, which has high heat resistance, allows for high-temperature applications that were previously difficult with headspace samplers because it doe not elute much bleed components even at 300 °C
