	Rapid fabrication of microextraction devices for direct determination of basic drugs in dried blood spots Ryšavá, Lenka ; Přikryl, Jan ; Dvořák, Miloš ; Malá, Zdeňka ; Kubáň, Pavel A 3D-printed cutter was designed for rapid fabrication of supported liquid membrane (SLM) extraction devices compatible with injection system of commercial capillary electrophoresis (CE) instrument. Low cost and single use microextraction devices were fabricated from polypropylene micropipette tips with high precision (dimension variances ≤ 3% RSD). Practical applicability of the microextraction devices was examined by in-line coupling of SLM extractions to CE for direct analysis of four model basic drugs in dried blood spot extracts. Excellent repeatability of the hyphenated technique was achieved (RSD ≤ 7.6%), transfer of analytes across the SLM ranged from 23 to 73% and limits of detection were as low as 0.07 μg/mL.

	Highly sensitive analysis of chlorophenols and sulfonamides in waters by electrophoretic focusion on inverse electromigration dispersion gradient with ESI-MS detection Malá, Zdeňka ; Gebauer, Petr ; Boček, Petr This work presents a new methodology for high-sensitivity analyses by capillary\nelectrophoresis (CE) with electrospray-ionization mass spectrometric (ESI-MS)\ndetection, based on electrophoretic focusing on an inverse electromigration dispersion\n(EMD) gradient. The technique is based on a robust electrolyte system providing a\ngradient of required properties, suitable for routine analyses of trace amounts of weak\nacids with pKa values between approx. 6.5 and 9. Examples analyses of several\nchlorophenols and sulfonamides are presented, with LODs around 3x10-9 M for spiked\ndrinking water without any sample pretreatment. Detailed record
	Capillary isotachophoresis with ESI-MS detection: Ultrahighly sensitve analysis of diclofenac and ibuprofen in waters Malá, Zdeňka ; Gebauer, Petr ; Boček, Petr This work shows that CE-MS can reach same sensitivity as HPLC-MS, when it is peformed in the ITP-MS mode. By combination of ITP-ESI-MS with an offline SPE preconcentration step and optimization of MS signal collection, LODs below 2x10-12 M can be reached, corresponding to of 0.6 ng/L of diclofenac (Dic) and 0.4 ng/L of ibuprofen (Ibu), compatible to that of SPE-HPLC-MS.

	Theoretical principles of capillary isotachophoresis in moving boundary systems Gebauer, Petr ; Malá, Zdeňka ; Boček, Petr This contribution provides fundamental theoretical background of ITP in moving-boundary systems. It is based on the approximation of capillary ITP as a 1D process and the general condition of ITP migration, i.e., the existence of a self-sharpening boundary capable to form a stack of zones moving with equal velocities.

	Capillary isotachophoresis of anions with electrospray-ionization mass-spectrometric detection Malá, Zdeňka ; Gebauer, Petr ; Boček, Petr We present ITP-ESI-MS as a powerful tool for selective and sensitive analyses of anionic analytes. Our extended concept of ITP includes besides regular and freeacid ITP also self-maintained ITP in moving boundary systems. Easy theory describes the system properties including their stacking-window diagrams. Simple ESIcompatible electrolyte systems allow flexible tuning with very satisfactory results as demonstrated on the example of analysis of pharmaceuticals in waters. Detailed record
	Highly sensitive determination of cationic pesticides in orange juice by capillary isotachophoresis-electrospray ionization - mass spectrometry with advanced electrolyte tuning Malá, Zdeňka ; Pantůčková, Pavla ; Gebauer, Petr ; Boček, Petr In this contribution we present an innovative way to easy, fast and highly sensitive analyses by capillary electrophoresis with electrospray ionization mass spectrometric (ESI-MS) detection. The new method is designed to be applied to ESI-compatible electrolytes (e.g. ammonium acetate) and offers advanced tuning of selectivity conditions within a wide range of analyte mobilities.

	Preparation of specific probes detecting prophages of serogroups A,B and F in lysogenic strains of Staphylococcus Aureus Doškař, J. ; Pallová, P. ; Pantůček, R. ; Rosypal, S. ; Růžičková, V. ; Pantůčková, Pavla ; Kailerová, J. ; Klepárník, Karel ; Malá, Zdeňka ; Boček, Petr On the basis of HindIII-restriction digest analysis of genomic DNAs, the S. aureus bacteriophages of the International Typing Set were divided into five clusters (A, F, Ba, Bb, and Bc). For each of the phage serogoups A, B, and F, common HindIII-restriction fragments of 3A, 53 and 77 phages were used for preparation of probes specific to the phages of all serogroups. These probes enable to detect up to three different prophages in a given lysogenic strain at the same time. Restriction enzyme maps of phages 3A, 53, and 77, each representing a different serogroup, were constructed. Detailed record
	Využití kapilární elektroforézy k analýze společných restrikčních fragmentů bakteriofágů Staphylococcus aureus Pallová, P. ; Kailerová, J. ; Doškař, J. ; Rosypal, S. ; Klepárník, Karel ; Malá, Zdeňka ; Boček, Petr Detailed record
