Halo or have the cake and eat it too

The HALO column allows fast seperation as in UPLC but with "normal" pressure below 400 bar and on regular HPLC systems. Based on Fused Core Technology, HALO Columns have a porous 0.5 µm layer fused to a solid silica core which reduces the diffusion path of the particle generating an only slightly higher back pressure.

Empty bottles with colourful caps

The cooperation with our partner company Glastechnik Gräfenroda GmbH started about three years after the fall of the Berlin Wall. Since these early days which haven't always been easy, business has prospered and meanwhile we produce vials which are shipped worldwide

Our latest product is our storage vial family to which we have added vials with 14.75 and 18.75 mm diameters. Thus we can offer you a good choice of storage vials incl. screw caps with PTFE liner.

The same procedure as every year or coumarin in cinamon cookies

Just before Christmas we receive the news that cinamon is encumbered with Coumarin and that the consumption of cinamon cookies in larger quantities is a serious health threat. There is a limit for coumarin (2 mg/kg product), which means it has to be analysed. For the analysis of natural samples, we recommend the new polymer based column from Shodex the ODP2 HP. This column does not only have a good good life span, because protein residues don’t “blot up” the phase it also remains efficient with constant back pressure.

Don't let a grain be the spanner in your frit

In analytical columns the particles get smaller and therefore the firt also has smaller pores. To avoid the frit to plug up, filtration of the sample prior to injection becomes a necessary routine and filters with 0.2 µm pore size are more frequently used in analytics. Which requirements should a good membrane filter meet?

Today's focus: the injector liner

The liner is the place where the sample is vaporised after injection. The Liner has to fulfill certain criteria to guarantee the reproducibility of the analysis. The FocusLiner does not only fulfill all criteria it also has the advantage that the quarz wool is securely held in place
