The permeation rate of the polymer used in G-Cal devices changes only 1%–3% per degree C, eliminating the need for a temperature-controlled chamber. We guarantee most G-Cal devices for 12 months of operating life (from the date of shipment ).\u003c\/p\u003e\n\u003cp\u003eMore than 100 different substances are available, including arsine, phosphine, and other pyrophoric chemicals, as well as gas-phase devices such as CO, CO2, and NO. Available permeation rates range from 200 ng\/min to 30,000 ng\/min and over. Each G-Cal device is individually calibrated and verified to generate a given output (ng\/min) vs. temperature.\u003c\/p\u003e\n\u003cp\u003eView the complete list of standard chemicals available[open G-Cal PDF File]; experimental and non-standard chemicals are also available on request.\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/www.vicimetronics.com\/pages\/contact-us\" title=\"Contact Us\" target=\"_blank\"\u003eContact us\u003c\/a\u003e for more information.\u003c\/p\u003e\n\u003cp\u003e\u003ca title=\"VICI Metronics G-Cal Devices\" href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0262\/9389\/5223\/files\/G-Cal_Permeation_Device.pdf?v=1621028674\" target=\"_blank\"\u003eDownload Brochure\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eView a sample of the Instruction Sheet Calibration Certificate that are provided for each G-Cal Permeation Tube product.\u003c\/p\u003e","brand":"VICI Metronics","offers":[{"title":"Hydrogen Sulfide \/ 200-0500 ng\/min","offer_id":39273993699383,"sku":"GC23-7002-C25","price":425.0,"currency_code":"USD","in_stock":true},{"title":"Carbonyl Sulfide \/ 200-500 ng\/min","offer_id":39273993732151,"sku":"GC23-7142-C25","price":425.0,"currency_code":"USD","in_stock":true},{"title":"Ammonia \/ 200-500 ng\/min","offer_id":39273993764919,"sku":"GC23-7012-C25","price":475.0,"currency_code":"USD","in_stock":true},{"title":"Water \/ 500-1500 ng\/min","offer_id":39273993797687,"sku":"GC23-7322-C50","price":425.0,"currency_code":"USD","in_stock":true},{"title":"Water \/ 1500-3000","offer_id":39273993830455,"sku":"GC23-7322-C50","price":425.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0262\/9389\/5223\/files\/G-CAL_GROUP_01.png?v=1684259097","url":"https:\/\/www.vicimetronics.com\/products\/g-cal","provider":"VICI Metronics","version":"1.0","type":"link"}
