The programmable temperature vaporizer (PTV) inlet for the 8890 and 7890B gas chromatography systems offers a variety of GC injection possibilities. It combines the benefits of split, splitless, cool on-column, and sample concentration (solvent elimination) modes. The PTV inlet allows both hot and cold injections and supports large-volume ...

Agilent programmed temperature vaporizer inlets combine the benefits of split, splitless, and on-column inlets. The sample is usually injected into a cool liner, so syringe needle discrimination does not occur. Then the inlet temperature is increased to vaporize the sample.

The GERSTEL Cooled Injection System is the most widely used PTV-type gas chromatographic inlet in the world. It is a true universal inlet, allowing you to perform up to 10 sample introduction techniques for gas chromatography with unsurpassed precision, accuracy, and robustness while eliminating analyte degradation, sample discrimination, and ...

2018年5月31日 · PTV 进样口在注射之前和注射过程中通过帕尔贴装置或强制气流（空气、液态N2 或液态CO2）主动冷却。 进样口的低温冷却降低了进样口的温度，足以对衬管中来自其它进样装置的气体进行热聚焦。 与传统的进样口相比，使用PTV 进样口实现辅助进样装置与毛细管柱的连接有显著的优点。 进样之后，PTV 进样口使用电加热器或预加热的压缩空气进行加热。 根据不同的设计，进样口的升温速率可以是抛物线形的（即以不控制的最大升温速率升至最高温度），也 …

Installing a PTV Inlet Agilent 6850 Series II Network GC System Accessories G3345B (Septumless) and G3346B (Septum) These instructions are divided into two parts: • Part 1 to prepare the Electronic Pressure Control ("EPC") module for later installation into the Agilent 6850 Gas Chromatograph ("GC")

The TITAN XL's use of PTV allows it to make LVI injections up to 1000µL while maintaining the ability to inject traditional 1µL split/splitless volumes used with a standard GC inlet. Universal GC inlet that provides split/splitles s and large volume injection in a single inlet.

The Thermo Scientific™ iConnect Programmable Temperature Vaporizing (PTV) Injector Module combines the discrimination-free performance of a cold injector with the robustness of vaporizing injectors. This PTV injector offers fast heating and cooling performance, making it ideal for trace analysis of dirty matrices and thermally labile compounds.

The Agilent Programmed Temperature Vaporization (PTV) Inlet System has five operating modes: •The split mode is generally used for major component analyses. •The pulsed split mode is like the split mode, but with a pressure pulse applied to the inlet during sample introduction to speed the transfer of material to the column.

The Programmable Temperature Vaporizer (PTV) inlet is an essential tool in analytical chemistry, enhancing the chromatographic process by allowing precise control over the temperature of sample vaporization. Its versatility makes it a preferred choice for laboratories seeking to improve the efficiency and accuracy of their analyses.
