syringe filter units 1. Syringe filter units Syringe filters are used for filtration of suspended matter from liquid sample or gases. Rapid purification and removal of particles is very simple: just place the filter on a syringe, and you are ready for filtration. Contamination of sensitive instrumentation by solid impurities can be avoided. Also the lifetime of chromatographic columns and equipmend can be increased. pore size

syringe filter units Selection of the appropriate filter FILTER SIZE: sample volume Filter size PORE SIZE: general applications, hplc columns with >3 µm particles uhplc, core-shell and hplc columns with <3 µm particles TYPE OF MEMBRANE: properties of the samples Aqueous, polar, hydrophilic with low particle load Aqueous, polar, hydrophilic with high particle load Semi-polar, e.g. HPLC eluents Sample contains proteins (low bonding capacity of the proteins) Sample contains proteins (high bonding capacity of the proteins) Strongly acidic or alkaline Organic, non-polar, hydrophobic with low...

solid phase extraction (spe) by macherey-nagel 4. Solid phase extraction (SPE) by Macherey-Nagel Solid-phase extraction (SPE) is a powerful method for sample preparation that is used today in most laboratories. The SPE shows its performance in a wide range of applications: environmental analysis, pharmaceutical analysis, organic chemistry and food analysis. SPE is used for three important tasks: enrichment of the analyte, removal of interfering components and change of the matrix of the analyte. Advantages of the SPE in comparison to classical liquid-liquid extraction: 1. Reduced...

thin layer chromatography (tlc) 5. Thin layer chromatography (TLC) The principle of TLC is known for over 100 years. TLC is still a popular technique in the laboratory for reaction, quality and identity control. Advantages of TLC are: • High sample throughput possible in a short time • No complex sample preparation required • Simple method without expensive instruments IMPLEMENTATION OF A TLC SEPARATION SELECTION OF THE SOLVENT: The solvent is selected by elution strength. The most appropriate solvent can be determined very easily. SAMPLE APPLICATION: A common method is to use a glass...
