Abstract:

The most important tool for molecular characterization of synthetic polymers is High-performance liquid chromatographic (HPLC) methods. Mean molar mass (MM) and molar mass distribution (MMD) of linear and branched homopolymers is easily determined by gel permeation (size exclusion) chromatography (GPC/SEC). GPC/SEC provides several other useful data such as limiting viscosity numbers, constants of viscosity law, sizes of macromolecules in solution - and even extent of preferential solvation of polymers in mixed solvents. Recent progress in GPC/SEC comprises improved instrumental hardware and data processing procedures. High sample throughput of the ultra-fast GPC/SEC enables acceleration of analyses, which is especially important in combinatorial material chemistry and in production control. Still, further improvements of the SEC method are needed, which include its hardware, especially columns and detectors, standardization of sample preparation, measurement and data processing. GPC/SEC exhibits excellent intra-laboratory repeatability, which evokes a notion of its high reliability. Recent series of the round robin tests, however, revealed surprisingly poor inter-laboratory reproducibility of results. Evidently, an accuracy of many GPC/SEC results may be rather limited. In most cases, GPC/SEC does not enable precise molecular characterization of complex polymer systems, which possess more than one distribution in their molecular characteristics. Typically, polymer mixtures, copolymers and functional polymers exhibit beside MMD also distribution in their chemical structure. To assess the above distributions, new HPLC procedures are developed. These are based on the controlled combinations of entropic (exclusion) and enthalpic (interaction) retention mechanisms within one column or in a series of independent separation systems. These approaches are denoted “coupled polymer HPLC” and “two- or multi-dimensional polymer HPLC”, respectively. Enthalpic retention mechanisms in HPLC of synthetic polymers include adsorption, partition, phase separation. We shall review recent progress and problems in GPC/SEC, as well as in the couple and two-dimensional polymer HPLC procedures and outline anticipated future development.

Abstract:

Academia has always used analytical techniques to characterize, test, and further promote the outcome of their respective research. Industry, on the other hand, has primarily utilized analytical science as a forensic tool to help solve product and/or process issues. Each endeavor has merit, and definitely is needed, especially in their respective genre. Each physical laboratory is constructed with these types of needs in mind. The Academic laboratory usually contains the equipment required to perform these analytical functions, since it is so central to their project work. Whereas, most industrial laboratories have a completely separated analytical department/lab area due to the fact that their major function is in support of the sales and/or manufacturing arm of the company.

These two endeavors need to be better aligned, such that industry can learn from Academia the importance of analytical sciences to build robust formulations/products during the development phase in order to eliminate the potential for problems after product launch. This will also allow for the building of a better understanding of the structure/property relationship.

Abstract:

Metabolomics plays an important role in discovering potential disease biomarkers from blood plasma or serum samples. Due to the distinctive complexity of whole blood as the sample matrix, either plasma or serum are used as the primary sample in metabolomics biomarker discovery research. During the transformation of whole blood into plasma or serum followed by extraction of targeted or non-targeted metabolites using conventional sample preparation techniques including solid phase extraction (SPE) and liquid-liquid extraction (LLE), a significant portion of the analytical information disappears, resulting in negligible success in discovering potential disease biomarkers. Fabric phase sorptive extraction (FPSE), a new generation sample preparation technology, has offered a paradigm shift approach in metabolomics sample preparation. FPSE innovatively combines the benefits of solid phase extraction (SPE) (works under exhaustive extraction principle) and solid phase microextraction (works under equilibrium extraction principle) into a single sample preparation technology platform. FPSE utilizes a flexible and permeable fabric substrate, coated with high-performance sol-gel sorbents as the extraction media. This uniquely designed extraction medium is capable of extracting target analyte(s) directly from whole blood. Due to the special geometry of FPSE medium (flexible, flat and permeable) and sponge-like porous architecture of sol-gel sorbents, rapid analyte mass transfer occurs between the bulk sample and the extraction medium, resulting in a near-exhaustive extraction within a fraction of time required for other comparable sample preparation techniques. FPSE is particularly suitable for analyzing target analytes e.g., metabolites, biomarkers directly from whole blood without requiring any protein precipitation or other pre-extraction sample cleaning/manipulation. After extracting the target analyte(s) directly from the whole blood sample, FPSE media is exposed to a small volume of organic/organo-aqueous solvent for eluting the extracted analyte(s). The low viscosity of the organic solvent, the capillary force of the fabric support and sponge-like porous sol-gel network allows fast diffusion of organic solvent into the FPSE medium for quick and complete recovery of the extracted analyte(s). As a result, FPSE completely eliminates time-consuming and error-prone solvent evaporation and sample reconstitution step often considered as an integral part of solid phase extraction/liquid-liquid e work-flow. During the solvent-mediated elution/back-extraction, any protein or matrix interferents adhered to the FPSE medium precipitates out and a final centrifugation of the resulting solution prior to injecting into the analytical instrument ensures clean particle-free highly concentrated target analyte(s). Fabric phase sorptive extraction has already developed a large number of sol-gel sorbents specifically suitable for polar metabolites/biomarkers such as sol-gel polyethylene glycol, sol-gel chitosan, sol-gel Carbowax 20M, sol-gel polycaprolactone-dimethylsiloxane-caprolactone to name a few. These high-efficiency sorbents have been found equally effective for analytes with a wide range of polarity. As a consequence, searching for a new disease biomarker from whole blood in presence of numerous endogenous and exogenous interferents is no longer a wishful thinking but an achievable reality. In the current talk, some new and fascinating data on metabolomics sample preparation using FPSE and a comparison between FPSE and conventional sample preparation techniques will be presented.

Abstract:

The imminent legal Cannabis Sector is projected to be worth 6 to 20 billion dollars in Canada alone. The highly regulated nature of this sector demands rigorous quality control measures that require advanced analytical mass spectrometry and other techniques to ensure product safety. The nature of the Cannabis plant and its current status as an illegal and controlled narcotic in many countries, add a level of complexity to the development of analytical protocols. This talk will highlight some of the challenges facing this sector and some of the approaches to overcome these. Specifically, issues with potency testing, quantifying medicinal dose delivery, pesticide testing, development of Certified Reference Materials and the importance of ISO 17025 accreditation and international standard development will all be discussed.
