AR Grade - Analytical Reagents generally complying with ACS specifications
Dioxins, Pesti-S, Furans, PCB Analysis – Analysed for their suitability in the detection of dioxins, furans & PCBs. ECD and NPD tested for pesticides residue analysis
Extra Dry - Dried solvent for routine synthesis in dry conditions, usually correspond to AR grade solvents which have been subsequently dried and micro-filtered. Display low content of metallic impurities.
GC Headspace – Optimized for accurate analysis of residual solvents. Evaluated against OVI standards to ensure the absence of interfering peaks in the GC chromatogram.
HPLC – Carefully prepared, bottled under inert gas and filtered through 0.2µm filters.
HPLC Supra – 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.
LC-MS – for routing quality work, analysed for low metallic level and good HPLC, UHPLC and MS performance. Filtered through 0.2µm filters.
LV-GC - Suitable for extraction-concentration analysis, analysed 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.
PAH - Highly purified, prepared and finally distilled in all glass systems to ultra-low residual level. These solvents are analyzed by HPLC using UV and Fluorimetric detection in the range of 16 standard polyaromatic hydrocarbons as per EPA 500 and 600 methods Peptide – Hi purity solvents specifically produced for peptide synthesis.
Spectrofluoropure – Guaranteed low fluorescence and/or low UV absorbance levels, also suitable for IR analysis
ULC-MS – Highest quality for very demanding work of chromatography, analysed for very high HPLC, UHPLC, SFC and MS performances, coupled with very low amounts of inorganic metallic contaminants. Filtered through 0.1µm filters.
