| Features and Benefits: | We have a vast portfolio of environmental PT schemes with "fit-for-purpose" samples to help you meet the needs of the laboratory. Our proficiency testing (PT) program is a benchmark to: • provide staff with an insight into their laboratory′s performance, to verify the accuracy and reliability of their testing process • provide a comparison of performance with that of other laboratories, nationally and internationally • test and educate staff, provide a better understanding of the impact of incorrect results and identify areas where there may be problems • provide an independent evaluation of laboratory performance • demonstrate to clients, colleagues and accreditation bodies that there is a commitment to quality |
| General description: | Hardness/TSS - Whole Volume - WP proficiency testing material is produced in accordance with ISO/IEC 17043:2010. Also referred to as non-Potable water or Water Pollution sample, this sample is produced according to TNI requirements. However, please note, this sample may include non-TNI analytes as well. The higher criteria from the TNI tables mimic the levels common to wastewater samples. The PT portfolio allows our test components to offer significant performance data to monitor and prove competency to customers, accreditation bodies or both. Supelco® is a global proficiency testing (PT) provider that manufactures best-in-class environmental and pharmaceutical PT products. Most water PT samples are available as concentrates or ready-to-use volumes giving the end-user flexibility in selecting samples that will fit their exact needs. Our WP program is designed to meet the quality assurance requirements, thereby ensuring the analytical competence of your laboratory. Type of PT Scheme: Water analysis - Water Pollution (WP) Matrix: Water Pollution/Wastewater Analyte/s: Values of analytes vary lot to lot. All information regarding the use of Hardness/TSS - Whole Volume - WP can be found in the reporting packet which will be available to download at PT Portal . |

| Preparation Note: | Description • This standard is packaged in a 500-mL polyethylene bottle containing approximately 500 mL of standard. • This standard is not preserved. • This standard can be stored at room temperature. Preparation Instructions • This standard has been prepared as a whole volume standard and is ready to analyze as received. • The hardness in this standard can be determined using either titration or calculation methods. • Be sure to shake this sample very well prior to taking an aliquot for the TSS determination. • It is strongly recommended that you analyze for TSS prior to removing aliquots for other analyses from the Hardness bottle. • If other analytes are to be measured prior to TSS, be sure to shake the sample very well prior to removing aliquots for any of the other parameters. • As this standard contains suspended solids, it is best to filter a portion of the standard prior to adding preservation or aspirating the sample into any instrument. • Shake the Hardness bottle very well prior to opening. • Remove aliquots for the tests that you are performing and analyze by your normal procedures. |
