Description	Mass spectrometry (MS) is being increasingly used for analysis of proteome complex samples. To remove matrix interferences and to concentrate analytes prior to a MS measurement, sample preparation is often necessary. A useful method for this purpose is Carrier Ampholyte Free-Isoelectric Focusing (CAF-IEF). In this paper CAF-IEF of ampholytes was performed on a commercial apparatus EA101 (Villa Labeco, Slovakia) equipped with a specially made column for samples of large volumes (up to 0.5 ml). A new continuous mode without voltage interruption or electrolyte replacement was developed. In this mode, a low molecular pI marker (PIM 7.4), low concentrations of myoglobin and insulin (16 mg/l), respectively, were concentrated, and then 5-ul fractions collected for off-line analyses. The total time of focusing was 66 minutes. Concentration of PIM 7.4 in the fractions was increased up to 75 times (determined by UV-VIS spectrometry).
