Solids in Wastewater Solids in Wastewater CRMs for Solids Analysis Use of ISO Guide 34 certified reference materials to QA your routine solids analyses has never made more sense. Our CRMs for solids are simply a good value: • All of our solids CRMs are easy to implement and use. There is no preparative step, simply shake the bottle well and measure the appropriate aliquot. Ready-to-Use Bottles TDS TS TSS Mid-Level Solids Concentrate 90 mg/L 120 mg/L 30 mg/L Supplied as a homogeneous powder for suspension of 1 gram to 1000 mL. Makes 8 Liters of standard.

High-Level Solids CRM Ready-to-Use Bottles TDS TS TSS 3000 mg/L 3500 mg/L 500 mg/L A whole volume multi-analyte standard for quality control analysis for 6 solids parameters. Each 100 mL aliquot contains: Total Solids 300 mg Total Dissolved Solids 250 mg Total Suspended Solids 100 mg Volatile Suspended Solids 31 mg Fixed Suspended Solids 70 mg Fixed Dissolved Solids 215 mg QCI-171 . . . . . . . . . . . . . . . . . 4 x 1 L Case . . . . . . . . . . . . . $150.00 QCI-055H . . . . . . . . . . . . . . 4 x 1 L Case . . . . . . . . . . . . . $130.00 • Finally, our solids CRMs are inexpensive to use. Each is supplied as a 4 x 1 Liter case and at the higher concentration level, the cost per QA test can be as low as $1.00. We hope you’ll see the value and give us a try.
