Quantitative Determination of Mg in Ai-Alloys by Ion-Exchange TLC

A Brief Review of Chromatography in Croatia

“…In 2006, at the twelfth ISSS Symposium in Lipica, Slovenia, Dr. Šegudović was proposed as the first Secretary of the CEGSS [14]. In the second half of the 20th century, chromatographers in Croatia were mainly dealing with thin-layer chromatography [15][16][17][18][19][20][21][22][23][24][25][26]. However, towards the end of the century, the situation began to change.…”

“…To date, 19 ISIC/ICS schools have taken place, and the high number of participants in the schools speaks to the need for such an event (Figure 3). In the second half of the 20th century, chromatographers in Croatia were mainly dealing with thin-layer chromatography [15][16][17][18][19][20][21][22][23][24][25][26]. However, towards the end of the century, the situation began to change.…”

Basic TLC Techniques, Materials, and Apparatus

“…A system comprising a computer, digital image scanner, and black-and-white and color printers was described for documenting visible TLC spots but not those detected under UV light (234). Commercial photographic and video documentation instrumentation for colored, fluorescent, and quenched zones is available from commercial sources, including Camag (235,236). Various paper brands were tested for printing and color stability characteristics and the effects on archiving of chromatograms produced from the Camag video system using an ink jet printer (237).…”

Pesticides

“…Validation was carried out on the video densitometric and slit-scanning determination of propham, chlorpropham, atrazine, diflubenzuron, tetramethrin, and a-cypermethrin for linearity, precision, and detection limit. Dark or moderately luminous video images gave more repeatable results than very bright images (217). The main advantages of video technology were speed, excellent archiving capability, and the fact that data can be stored together, edited, and used for many tasks (215).…”
