Even trace-level impurities can contribute to degradation of solid electrolyte interfaces, consumption of lithium ions, or gas formation\u2014effects that compromise both efficiency and safety.<\/p>\n\n\n\n<p>As battery materials continue to evolve, analytical approaches must provide both high sensitivity and high-confidence identification.

In DMC, impurities may include oxygenated compounds, hydrocarbons, and nitriles, many of which arise from synthesis or handling processes.<\/p>\n\n\n\n<p>These compounds can co-elute or exist at levels below typical detection thresholds, making comprehensive analysis difficult with a single analytical technique. In addition, electron ionization (EI) spectra do not always provide a clear molecular ion, complicating compound confirmation.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-group has-global-padding is-layout-constrained wp-block-group-is-layout-constrained\">\n<div class=\"wp-block-group has-global-padding is-layout-constrained wp-block-group-is-layout-constrained\" style=\"margin-top:0\">\n<hr class=\"wp-block-separator has-text-color has-sl-1-color has-alpha-channel-opacity has-sl-1-background-color has-background has-base-100-color has-base-100-background-color is-style-default\" style=\"margin-top:60px;margin-bottom:60px\">\n<\/div>\n\n\n\n<h2 class=\"wp-block-heading is-style-h2-style\">Sensitivity + Confidence: A Complementary Strategy<\/h2>\n\n\n\n<p>Two GC-MS systems were utilized to create a complementary workflow for this analysis:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong><a href=\"https:\/\/dev26.lecowebtest.com\/instrument\/benchtop-gc-tofms\/\" data-type=\"instrument\" data-id=\"2168\">Pegasus BTX (GC-TOFMS)<\/a><\/strong>\u00a0for high-sensitivity detection<\/li>\n\n\n\n<li><strong><a href=\"https:\/\/dev26.lecowebtest.com\/instrument\/high-resolution-gc-ms-hrt\/\" data-type=\"instrument\" data-id=\"2252\">Pegasus HRT (high-resolution GC-MS)<\/a><\/strong>\u00a0for accurate mass confirmation<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-default is-cropped wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\" style=\"margin-bottom:var(--wp--preset--spacing--2-xl)\">\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\" data-id=\"3123\" src=\"https:\/\/dev26.lecowebtest.com\/wp-content\/uploads\/2026\/03\/leco-btx-gc-ms-with-autoloader-1024x576.webp\" alt=\"LECO Pegasus BTX GC-MS system with autoloader\" class=\"wp-image-3123\" srcset=\"https:\/\/dev26.lecowebtest.com\/wp-content\/uploads\/2026\/03\/leco-btx-gc-ms-with-autoloader-1024x576.webp 1024w, https:\/\/dev26.lecowebtest.com\/wp-content\/uploads\/2026\/03\/leco-btx-gc-ms-with-autoloader-300x169.webp 300w, https:\/\/dev26.lecowebtest.com\/wp-content\/uploads\/2026\/03\/leco-btx-gc-ms-with-autoloader-768x432.webp 768w, https:\/\/dev26.lecowebtest.com\/wp-content\/uploads\/2026\/03\/leco-btx-gc-ms-with-autoloader-18x10.webp 18w, https:\/\/dev26.lecowebtest.com\/wp-content\/uploads\/2026\/03\/leco-btx-gc-ms-with-autoloader.webp 1280w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\" data-id=\"3264\" src=\"https:\/\/dev26.lecowebtest.com\/wp-content\/uploads\/2026\/03\/leco-pegasus-hrt-high-resolution-gc-tof-ms-1024x576.webp\" alt=\"LECO Pegasus High-Resolution GC-TOF-MS\" class=\"wp-image-3264\" srcset=\"https:\/\/dev26.lecowebtest.com\/wp-content\/uploads\/2026\/03\/leco-pegasus-hrt-high-resolution-gc-tof-ms-1024x576.webp 1024w, https:\/\/dev26.lecowebtest.com\/wp-content\/uploads\/2026\/03\/leco-pegasus-hrt-high-resolution-gc-tof-ms-300x169.webp 300w, https:\/\/dev26.lecowebtest.com\/wp-content\/uploads\/2026\/03\/leco-pegasus-hrt-high-resolution-gc-tof-ms-768x432.webp 768w, https:\/\/dev26.lecowebtest.com\/wp-content\/uploads\/2026\/03\/leco-pegasus-hrt-high-resolution-gc-tof-ms-18x10.webp 18w, https:\/\/dev26.lecowebtest.com\/wp-content\/uploads\/2026\/03\/leco-pegasus-hrt-high-resolution-gc-tof-ms.webp 1280w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n<\/figure>\n\n\n\n<p>The <a href=\"https:\/\/dev26.lecowebtest.com\/instrument\/benchtop-gc-tofms\/\" data-type=\"instrument\" data-id=\"2168\">Pegasus BTX<\/a> enables detection of impurities at below parts-per-billion levels, ensuring that even low-abundance analytes are captured.<\/p>\n\n\n\n<p>Following detection, the <a href=\"https:\/\/dev26.lecowebtest.com\/instrument\/high-resolution-gc-ms-hrt\/\" data-type=\"instrument\" data-id=\"2252\">Pegasus HRT<\/a> provides high-resolution, accurate mass data in both EI and positive chemical ionization (PCI) modes.
