{"title":"Gas Chromatography PLOT Columns","description":"\u003cp class=\"MsoNormal\"\u003eGas chromatography PLOT (Porous Layer Open Tubular) columns are purpose-built for the efficient separation of permanent gases, light hydrocarbons, and volatile compounds that are difficult to retain on conventional capillary columns. Featuring a porous adsorbent layer bonded to the inner wall of the column, PLOT columns deliver exceptional retention, sharp peak shapes, and reliable separation of low-molecular-weight analytes such as CO₂, CO, methane, ethane, propane, and light olefins.\u003c\/p\u003e\n\u003cdetails\u003e\n  \u003csummary\u003eMore +\u003c\/summary\u003e\n\u003cp\u003eOur selection of PLOT columns from Quadrex is engineered for high performance, consistency, and long-term stability. PLOT columns are widely used in applications including refinery gas analysis, natural gas characterization, environmental monitoring, industrial gas quality control, and specialty research environments where accurate separation of light gases is critical. Choosing the right PLOT column is essential for achieving reproducible results and minimizing downtime.  Explore our Quadrex PLOT column offerings and achieve confident, high-resolution separations for even the most challenging light-gas applications.\u003c\/p\u003e\u003c\/details\u003e","products":[{"product_id":"ch-100043","title":"CH-100043 - GC Column PLT MoleSieve 5A, 30 m x 0.53 mm ID, 25 µm Film","description":"\u003cp\u003eThe analysis of permanent gases is an important application in the petrochemical industry. Quadrex offers the PLT-5A molecular sieve PLOT capillary column as a replacement for the traditional packed molecular sieve column. A capillary PLOT column offers the advantage of a faster turn-around time between analyses as well as the added benefit of faster regeneration of the adsorbent layer.O2, N2, CO, and CH4 are typically separated in six minutes. In addition, the important O2\/Ar separation can be achieved using this column at sub-ambient temperatures.We use a proprietary process which insures column-to-column reproducibility and a unique binding agent which eliminates adsorbent layer degradation which can cause contamination of valves and detectors.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eReliable permanent gas analysis\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eRugged layer of molecular sieve\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eExcellent thermal stability to regenerate adsorbent layer\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eSimilar column types: GS-Molesieve, Rt-MSieve 5A, AT-Mole Sieve\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"afpproducts","offers":[{"title":"Default Title","offer_id":44989655843006,"sku":"CH-100043","price":1811.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0647\/6251\/1550\/files\/Quadrex-HiRes.png?v=1743698267"},{"product_id":"ch-100044","title":"CH-100044 - GC Column PLOT-Q, 30 m x 0.53 mm ID, 30 µm Film","description":"\u003cp\u003eQuadrex offers a Q-type PLOT column coated with divinylbenzene copolymer which is ideal for the analysis of natural gas, refinery gas, amines, and sulfur gases.
