10-32 and 1/4-28 threaded ThermoFlare ports, DIONEX recommends the use of Tefzel® liquid lines with a PEEK ferrule/bolt fitting on one end and a 1/4-28 ThermoFlare fitting on the other end. See, “DIONEX Liquid Line Fittings,” for detailed instructions on purchasing or making these lines. - Page 6 Typical Backpressure Standard Flow Rate Maximum Flow Rate Column MPa at 30 ºC mL/min mL/min TCC-LP1 < 70 (0.48) 0.50 4-mm TCC-ULP1 < 45 (0.31) 0.50 5-mm TCC-XLP1 < 30 (0.21) 0.50 6-mm Doc.

TCC-LP1. Alternately, you can use a separate positive displacement pump such as the Dionex DQP pump (P/N 035250). When using a pump, ensure that a high pressure damper is used. Pump flow rates of approximately 3 mL/min can be used while maintaining sample concentration efficiencies high enough to ensure good quantification. - Page 9 Figure 3 shows the configuration for sample loading using a Rheodyne valve.

C. 1 µg/L working standard solutions may be prepared by diluting 1 mL of the 1 mg/L stock standard to 1,000 mL. These working standards are stored in polystyrene containers. They are stable up to 8 days, but Dionex recommends daily preparation since standard response is critical in the results of your analysis. -

75% of this value. This will ensure that there is a safety margin built into the concentration process in case a sample in a series of concentration experiments has a slightly higher ionic concentration. FIGURE 5 Linearity of Lithium Concentrator Injection Doc. No. 034973-06 ©2005 DIONEX September 2005... - Page 12 F. Record the resulting chromatogram and calculate the breakthrough volume, as shown in Figure 7, “Typical Data Obtained in the Determination of the Breakthrough Volume.” G. For practical purposes, the volume concentrated should be below 75% of the breakthrough volume. Doc. No. 034973-06 ©2005 DIONEX September 2005...
