LMNaOH (2 mm). Step II: Rinse cycle 2: electrolyte A, B, or C (2 mm). Step III: Set detector: select desired iL. Step IV: Sampling. 1 s hydrodynamic. Step V: Operating voltage: + 25 kV. Run time: 30 mm. Capillary dimensions: 50 urn x 57 cm (50 cm to detector). 1. Free Solution CE A list of common buffers and pH ranges used in FSCE is given in Table 2. The inorganic electrolytes, such as phosphate and borate, are commonly used at concentrations in the area of 10-50 mM. Higher concentrations are not generally possible because of internal heating problems within the capillary, but can improve peak shape.

Step 4: Inject electrolyte or water (1 s). Step 5: Separate. Precision in Quantitative Analysis 67 The purpose of step 4 is to wash the capillary exterior to avoid any crosstransfer of sample solution. 11. Capillary Cutting If the capillary end is jagged, sample solution may be irreprodwcibly transferred from the sample solution. It is therefore important to break the capillary using a cutting stone or a diamond-tipped cutter. If this source of imprecision 1s suspected, examine the capillary tip using an appropriate eyepiece.
