The right atmosphere for
spectrophotometry
A frequent requirement in the study of anaerobic exercises is the creation of a specific atmosphere in a spectrophotometer cell
How can you create a specific atmosphere in a spectrophotometer cell without pumps, tubing, gas manifolds, etc? This is a frequent requirement in the study of anaerobic processes, and the GL14 range of anaerobic cells from Starna provides a simple, elegant solution to the problem These cells are sealed either with a screw cap, or, most conveniently, with a septum cap, through which syringe needles can be inserted to allow filling, extraction or setting up a flow of gas

CRMs for far-UV validation
Certified reference materials extend the instrument qualification range to 200nm, unlike most commercially-available UV CRMs which have lower limits around 240nm
This arrangement is easy to use, requires a minimum of peripheral equipment and uses only small volumes of gas.
GL14 cells have been found to be ideal for applications like the determination of cytochrome P 450, where absorbance measurements have to be taken under a carbon monoxide atmosphere.
Internal pressures up to 5bar can be accommodated.
The cells are available with a range of path lengths up to 50mm and in all the usual formats, including microcell, fluorimeter and cylindrical.
They can be supplied with different window materials depending on the application, and are assembled using Starna's fully fused construction technique.
