Description
CHROMABOND columns PTL are solid-phase extraction columns designed for use with solvents that are lighter than water. Each column has a 3 mL volume and is supplied ready for laboratory sample-preparation steps in which a lighter organic phase must be handled separately from an aqueous layer. These CHROMABOND PTL units from manufacturer Macherey-Nagel form part of the chromatography accessories portfolio and address phase-handling needs that arise during liquid–liquid related SPE or extract work-up. The 3 mL format provides a practical working volume for collecting or processing the lighter solvent fraction under controlled conditions. A pack contains 100 columns, supporting higher-throughput series as well as repeated method trials. In analytical workflows, PTL columns help organise solvent layers when the organic phase floats on water, reducing the risk of cross-contamination between phases during transfer or further clean-up. Laboratories performing extraction, enrichment or solvent exchange steps ahead of chromatographic analysis can incorporate the 3 mL CHROMABOND PTL columns into manual or semi-automated sample-preparation schemes wherever solvents lighter than water must be managed reliably.
This article is part of SPE cartridges & columns, in SPE & sample preparation.

Questions about Chromab. columns PTL, 3 mL
What is this article?
Chromab. columns PTL, 3 mL is the article on this page. Luminix Health distributes Macherey-Nagel 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.
What should I check before I order?
