Let\u2019s begin by exploring what a particle trap is and how it works.&nbsp;<\/p>\n\n\n\n<p>Particle traps are PDMS-coated columns designed to catch any particles that are released from a PLOT column.&nbsp;For atmospheric pressure outlets such as valves, flow switching devices, or even FID and TCD detectors, half a meter to two meters of a particle trap column with the same ID as the PLOT column is sufficient.&nbsp;Whereas for mass spec detectors, a column length of five meters with a&nbsp;0.18 or&nbsp;0.25 millimeter ID is recommended. Not only will this aid in particle trapping, but it will also help manage the flow into the MS.&nbsp;<\/p>\n\n\n\n<p>Prior to installing the particle trap, condition the PLOT column out of the detector using&nbsp;three&nbsp;times higher the column flow than your application suggests.&nbsp;We recommend programming the GC oven to heat up at 5\u00b0C&nbsp;per minute up to the column\u2019s maximum temperature. Once reached, hold this temperature for at least an hour\u2014this should allow any loose particles to elute from the column.<\/p>\n\n\n\n<p>Now that conditioning is complete, it\u2019s time to cut the end of the PLOT column and the particle trap column. A scoring wafer should be used to achieve a straight, square cut, which is essential to correctly connect the Press-Tight connector.&nbsp;Next we\u2019ll prepare the PLOT column by lightly tapping, or flicking the end of the column with your fingers to remove any loose particles.&nbsp;Clean the ends of the PLOT column and the particle trap with a lint-free wipe moistened with methanol or isopropanol to remove&nbsp;any&nbsp;finger oils and&nbsp;any&nbsp;other impurities.&nbsp;<\/p>\n\n\n\n<p>Now we\u2019ll connect the columns together using the Press-Tight connector.&nbsp;While holding the connector in one hand, gently insert the PLOT column end into the connector until it is gripped firmly.&nbsp;Be careful not to press too hard or the column end will crush.&nbsp;And now we\u2019ll simply repeat the process with the particle trap, gently inserting it into the other end of the connector.&nbsp;A&nbsp;continuous brown ring where the column end compresses inside the connector indicates a proper connection.&nbsp;<\/p>\n\n\n\n<p>Visually inspect both seals and leak check the connections using an electronic leak detector. If you notice a leak, cut a small portion of the column in question and reconnect.&nbsp;And that\u2019s it\u2014you\u2019re ready to go. Decrease the column flow and you\u2019re set to start your analysis.&nbsp;<\/p>\n\n\n\n<p>Please like and subscribe for more helpful content and thank you for joining us for this Restek Tip.<\/p>\n\n\n\n<div style=\"height:100px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n","protected":false},"excerpt":{"rendered":"<p>What does a particle trap do?
