Qmx Laboratories can prepare custom multi-element calibration standards to exact specifications accredited to ISO 17025 and ISO Guide 34. Indicate the desired elements and their concentrations, together with the desired matrix, and the company will recommend a mix stability for a minimum of 12 months (reduced shelf life for concentrations less than 10 ppm). A certificate of analysis,reporting the actual values and not simply the calculated values, accompanies each standard.
Simply send us a list of elements, concentrations, matrix and quantity and we will prepare a quotation for your specific requirements or click here for our simple Custom Mix online form.
