Description
BTX test mixture, concentration 10 ng/µL, is a methanol-based analytical standard for chromatography laboratories working with benzene, toluene and xylene-type analytes. Supplied at a defined concentration of 10 ng/µL in methanol, the preparation supports calibration checks, method verification and routine system performance testing in GC and related workflows. Each pack contains 1 ml of solution and is ADR/IATA de minimis exempted, which eases shipment and internal logistics under the applicable limited-quantity rules. The product comes from manufacturer Macherey-Nagel as a single-unit pack intended for analytical use rather than bulk preparation. It is non-sterile and exhibits the hazard characteristics of methanol solutions, including flammability and acute toxicity, so handling must follow laboratory safety practice and the accompanying safety data. This BTX test mixture provides a convenient, small-volume format at a fixed 10 ng/µL level for laboratories that require a ready methanol matrix standard for BTX-related chromatographic applications.

Questions about BTX test mixture, conc. 10 ng/µL
What is this article?
BTX test mixture, conc. 10 ng/µL is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in Chromatography accessories, inside Vials, caps & septa, in Chromatography equipment.
These are the small chromatography parts that are not a column, a vial or a syringe: vial racks, solvent filters, waste caps, ferrule kits. A solvent inlet filter is what keeps the pump from swallowing particles out of the bottle.
An autosampler vial is the small closed bottle a chromatograph picks up. The neck is crimp, screw or snap, and the cap and the septum have to be that neck. The septum is the part the needle pierces. A soft septum reseals. A septum that is wrong for the solvent swells or sheds particles into the sample. Inserts reduce the volume when the sample is scarce. The separation they feed is described with IUPAC names and PubChem data.
Which category should I open next?
The category is Vials, caps & septa. The sub-category is Chromatography accessories. The catalogue is Chromatography equipment.
Shelves beside this one are Vial caps & septa, Autosampler vials, Crimpers & decappers and Vial inserts.
What should I check before I order?
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
