Are you going to be at PREP 2011 in Boston?
PREP 2011 is the premier arena for the presentation and discussion of the latest developments in preparative chromatography, separation science and technology.
Join scientists and media manufacturers from around the world who will focus on presenting some of the most cutting-edge areas of preparative and process chromatography; and see how the latest products and technologies are driving the pace of innovation in scientific research.
In the city hailed as being the “most European” of all American cities, YMC will fit in nicely with the events motto. YMC will exhibit the latest and most advanced media. Amongst them are:
YMC-Triart, the hybrid material with excellently balanced selectivity and pH stability of pH 1 to 12!
The YMC*Gel HG-series: Silica based material with improved mechanical stability at a very attractive price.
YMC BioPro: the IEX material featuring high dynamic binding capacity at high flow rates for exceptionally efficient processes.
We will be happy to welcome you at our booth and discuss how these and other YMC media can help improve your preparative separation process.
Use the opportunity and arrange an appointment in the run-up-to PREP. Should you not be able to join us at PREP, we can always arrange a visit to your company.

Gradient elution of the 16 EPA-PAH with Methanol / Water
Polycyclic Aromatic Hydrocarbons (PAH) are compounds of great interest, as they are widespread in the environment and have been partially identified as carcinogenic, mutagenic and teratogenic. Monitoring these contaminants in soil, water, air and other matrices is routine for many laboratories.
HPLC with gradient elution of PAHs using acetonitrile as organic modifier is a very common method because of its advantageous chromatographic characteristics.
However, for some users it is desirable to avoid the use of acetonitrile, especially because of the supply issues that have occurred in the past. For these customers we present the separation of the 16 PAHs according to EPA 610 using a methanol / water gradient with a YMC PAH-column.
The separation was successful with high resolution (RS) even for the critical peak pairs 7/8 (RS = 1.97) and 14/15 (RS = 2.85). When carrying out the separation with this eluent, attention must be drawn to the change of the elution order of benzo(ghi)perylene (Peak 14) and dibenzo(ah)anthracene (Peak 15) when compared to the elution order using an acetonitrile / water gradient.
