{"product_id":"oreas-723b","title":"OREAS 723b","description":"\u003cdiv class=\"product-description\"\u003e\u003cp\u003eOREAS 723b is a certified reference material (CRM) prepared from a high-grade \u003cbr\u003e\r\ngraphite concentrate and a blend of granodiorite sourced from Oaklands Quarry, \u003cbr\u003e\r\nTullamarine, located in northern Melbourne, Victoria.\u003cbr\u003e\r\nThe granodiorite is a coarse-grained intrusive igneous rock composed \u003cbr\u003e\r\npredominantly of quartz, plagioclase feldspar, and biotite, characteristic of \u003cbr\u003e\r\nSilurian-aged granitoid formations within the Melbourne Zone of Victoria.\u003cbr\u003e\r\nOREAS 723b has been characterised for Total Graphite Carbon (TGC) by dilute \u003cbr\u003e\r\nacid (HCl) digestion followed by roasting at approx. 425 °C, then analysis by \u003cbr\u003e\r\ninfrared combustion furnace. Nineteen commercial analytical laboratories \u003cbr\u003e\r\nparticipated in the certification program of this CRM.\u003cbr\u003e\r\nHomogeneity was evaluated using 12 subsamples analysed in a single \u003cbr\u003e\r\nlaboratory. ANOVA was applied to duplicates from six test units to compare \u003cbr\u003e\r\nwithin- and between-unit variances, providing a statistical measure of batch \u003cbr\u003e\r\nhomogeneity.\u003c\/p\u003e\u003c\/div\u003e\u003cdiv class=\"product-specs\"\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eState:\u003c\/strong\u003e primary\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMatrix:\u003c\/strong\u003e granodiorite\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMineralisation:\u003c\/strong\u003e crystalline vein\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCRM Group:\u003c\/strong\u003e Graphite\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\u003cdiv class=\"certified-values\"\u003e\n\u003ch3\u003eCertified Values\u003c\/h3\u003e\n\u003ctable class=\"analyte-table\"\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eAnalyte\u003c\/th\u003e\n\u003cth\u003eCertified Value\u003c\/th\u003e\n\u003cth\u003e1SD\u003c\/th\u003e\n\u003cth\u003e95% CL Low\u003c\/th\u003e\n\u003cth\u003e95% CL High\u003c\/th\u003e\n\u003cth\u003eMethod\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\u003ctr\u003e\n\u003ctd\u003eC-(Graphite), Carbon, graphitic (wt.%)\u003c\/td\u003e\n\u003ctd\u003e6.10\u003c\/td\u003e\n\u003ctd\u003e0.311\u003c\/td\u003e\n\u003ctd\u003e5.89\u003c\/td\u003e\n\u003ctd\u003e6.32\u003c\/td\u003e\n\u003ctd\u003eInfrared Combustion\u003c\/td\u003e\n\u003c\/tr\u003e\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e","brand":"OREAS","offers":[{"title":"10g Sachet","offer_id":44748108857480,"sku":"723b","price":8.55,"currency_code":"USD","in_stock":true},{"title":"500g Jar","offer_id":44748108890248,"sku":"723b-2","price":322.5,"currency_code":"USD","in_stock":true}],"url":"https:\/\/oceanrmc.com\/tr\/products\/oreas-723b","provider":"Ocean RMC","version":"1.0","type":"link"}
