Description
Surfactant exchange column according to DIN 38409-23 (blow-out column) is a complete exchange column equipped with PTFE stopcocks for standardized water and wastewater analysis. DIN 38409-H 23 specifies a method for determining bismuth-active substances in wastewater; required apparatus includes a surfactant exchange column as referenced in the standard. Normative linkage is to the German standard methods for the examination of water, wastewater and sludge, and the analytical procedure is carried out in accordance with DIN. This chromatography-related laboratory column from manufacturer Landgraf HLL supports the separation and sample-preparation steps associated with surfactant determination under the cited protocol. PTFE stopcocks provide chemical resistance suited to aqueous analytical work. Supplied as one complete unit, the column is intended for environmental, municipal and industrial laboratories performing routine DIN-based testing for bismuth-active substances in wastewater matrices.
This article is part of Chromatography standards (GC, HPLC, pesticides), in Analytical standards & reference materials.

Questions about Surfactant exchange column according to DIN38409-23 Blow-out column
What is this article?
Surfactant exchange column according to DIN38409-23 Blow-out column is the article on this page. Luminix Health distributes Landgraf HLL for laboratory use. It sits in SPE cartridges & columns, inside SPE & sample preparation, in Chromatography equipment.
An SPE cartridge holds a bed of sorbent. Bed mass, sorbent chemistry and volume are the specification. A 100 mg C18 cartridge and a 1 g C18 cartridge take different sample loads and different elution volumes. The method names all three.
Solid-phase extraction holds a compound on a sorbent while the rest of the sample is washed away, then releases it in a small volume. The sorbent, the bed mass and the solvents are the method. Silica, ion exchangers and polymer phases do different jobs. A flash column is the same idea scaled toward purification rather than trace cleanup. The molecules are on PubChem, named by IUPAC.
Which category should I open next?
The category is SPE & sample preparation. The sub-category is SPE cartridges & columns. The catalogue is Chromatography equipment.
Shelves beside this one are Sorbents, silica gel & ion exchangers and Flash, empty & glass chromatography columns.
