Splitless time

Web1 Oct 2016 · A tailing solvent peak during splitless injection indicates a poorly optimized splitless time. Too long a splitless time causes solvent peak tailing because not enough of the solvent is vented away and instead enters the column. Whereas too short a splitless time results in loss of early eluted analytes.

WebYou can see the effect of splitless purge valve time on peak response for a volatility range of PAHs (naphthalene being relatively volatile, benzo [ghi]perylene being relatively involatile), including the EFSA PAH4, in the chart below. A properly set purge valve time becomes even more important when analyzing dirty "real world" samples. WebAs splitless injections have inherently lower total gas pressure in the inlet (only the carrier flow is passing through the liner) and as the residence time of the sample solvent within the inlet is higher, splitless injection is considered to have a higher risk in terms of injection backflash and inlet contamination.

WebSplitless: Not split, but only for 1 to 2 minutes after injection Total volume injection (Direct injection): There is no splitting mechanism. Cold Injection Cold on-column injection (OCI) Programmed temperature vaporization (PTV) Reference Information Guidelines for Applicable Samples, Injection Volumes, and Columns for Each Injection Method WebThe key feature of a splitless injection is that all the carrier gas flow is directed to the column and the splitless valve is closed during injection. This allows for maximum recovery of the injected sample, making splitless injections ideal for trace level analyses.

Web6 Feb 2014 · Splitless Time: This is the time span for which the split vent is kept closed during the process. It has to be precise. If the duration is kept small, the entire sample won’t get transferred to the column, and the process won’t take place correctly. Contrastingly, the extensively longer splitless time can also result in complications.
