GRADES DESCRIPTION
ULC/MS - CC/SFC
Highest quality for very demanding work of chromatography, analyzed for very high HPLC, UHPLC,
SFC and MS performances, coupled with very low amounts of inorganic metallic contaminants.
, Filtered through 0.1 µm filters.
LC-MS
) For routine quality work, analyzed for low metallic level and good HPLC, UHPLC and MS performance.
Filtered through 0.2 µm filters.
,
HPLC Supra-gradient (Reag. EP/BP/USP)
Our supra-gradient quality often guarantees unique specifications including ultra-low fluorescent
) impurity levels, outstanding high UV transmission, minimum peak impurities, and very low drift in
, gradient HPLC.
HPLC-S
) Standard gradient quality for higher analytical demand.
H, PLC-R
Regular quality, satisfactory for most standard isocratic and routine gradient work
H,) PLC Preparative
Basic alternative for preparative HPLC work. Although not always printed in this catalogue, this quality is
available for most solvents. Please inquire.
,)
HPLC, HPLC-PLUS
Carefully prepared, bottled under inert gas and filtered through 0.2 µm filters.
)
LV-GC for organic trace analysis
, Suitable for extraction-concentration analysis, analyzed for GC-FID, -ECD and –NPD suitability as well
as for PDA performance for the analysis of PAH, GC-Capillary analysis, minute residue analysis, heavy
hydrocarbon and mineral oil index analysis. The solvents display high transmittance and low level of
) fluorescent impurities.
,
Dioxins, Pesti-S, Furans, PCB's analysis
Analyzed for their suitability in the detection of Dioxins, Furans & PCB’s. ECD and NPD tested for
) pesticide residue analysis.
Headspace, Purge & Trap
, Headspace and Purge & Trap grade solvents are optimized for accurate analysis of residual solvents.
The purity of our solvents specifically evaluated by analysis against OVI standard to ensure the absence
of interfering peaks in the GC chromatogram.
)
DNA synthesis
, Standard DNA phosphoramidites, RNA phosphoramidites, specialty Amidites & Modifiers, synthesis
supports, columns, ancillary reagents & formulations for DNA & RNA synthesis.
