Liquid Analysis

Liquid Chromatography (LC), High Performance LC (HPLC) and LC/MS, Ion  and Chromatography (IC)

CDE maintains a robust arsenal of highly sensitive and analyte-specific liquid chromatographic instrumental capabilities utilized for ultra sensitive quantitation and identification of molecular and ionic chemical constituents. Among these, a Waters AllianceTM High Performance Liquid Chromatography system is particularly useful for the analysis of organic moieties. Detection modes include spectroscopic (photo diode array), and mass selective through incorporation of an interfaced quadrupole mass spectrometer (Waters Micromass ZQTM) which combines the physical separation capabilities of HPLC with the mass analysis capabilities of mass spectrometry. Ionic constituents (e.g. anions, cations, transition metals, etc.) are readily analyzed in solution at the sub part per million level utilizing ion chromatographic methodologies utilizing a state of the art DionexTM ICS 3000 system equipped with suppressed conductivity and pulsed amperometric detection modules.

Chromatograph methods are among the most widely used techniques for the analysis of polymer composition and for the determination of the molecular weight distribution. Further, the instrumentation described above is well suited for experimental designs aimed at determining structure-property relationships in polymer degradation studies i.e. those involving thermal and radiolytically aged polymer samples.

Inductively Coupled Plasma - Optical Emission (ICP/OES) and Mass Spec (ICP/MS)

Capabilities include elemental and isotopic analysis at the major, minor, trace, and ultratrace levels for most elements across the periodic table. Instrumentation include several Perkin Elmer Optima 4300 DV ICP-OES (TA59/0001 and TA46/24) , Perkin Elmer Elan 6100 ICP-MS (TA59/0001), Thermo Element 2 High Resolution ICP-MS (TA46/24), and a New Wave laser ablation system for direct solids sampling (TA46/24). We also have a Leco CHN elemental analyzer and total organic/inorganic carbon analyzer (TA46/24). To support the elemental analysis capabilities we have several Milestone ETHOS microwave ovens with both atmospheric and high-pressure vessels and sample grinding and ball milling systems (TA59/0001 and TA46/24).
