DETERMINATION OF THE QUALITY OF ACTIVE INGREDIENTS IN PAIN KILLERS USING GC-MS
Elizabeth N.M Murago1, Nathan Oyaro1, Anthony N. Gachanja, Onditi O. Anam, Felix M. Mawili, Steve Lancaster

From this study, the pain killers sampled were found to have large error bars suggesting that there exist counterfeit drugs in the market. The brands mostly affected for analysis of acetaminophen were panadol, action, P500, P5500, elymol and neladol. The error bars for caffeine analysis were quite low indicating that all tablets either counterfeit or original maintained the same amount of this active ingredient.

DETERMINATION OF ESSENTIAL AND HEAVY METALS IN KENYAN HONEY BY ATOMIC ABSORPTION AND EMMISSION SPECTROSCOPY
A. Mbiri, A. Onditi, N. Oyaro

Generally, honey samples recorded very low concentrations of As compared to the other heavy metals determined in this study. The highest concentration of As was recorded in honey sample from Nairobi with a value of 0.03±0.01 ppm. All the values recorded were within the KEBS permitted value of 0.5 ppm in food according to Kenya Bureaue of Standards, 1996.

Prospecting For Iron and Titanium Using Termitaria
Kinachu James. G, Kiptoo Jackson. K, Onditi Anam.O.

This study demonstrated elevated levels of the two metals (that is iron and titanium) in termitaria soil compared to the surrounding soils. Termitaria are very important bioturbators and can therefore be used as preliminary step in mineral prospecting since they provide an indication of the potential of the positive anomaly, and enables a judgment on the scale of the metal accumulation

Pathogenesis and Clinical Presentation of Throat Candidiasis in Durrës area, Albania
PhD Cand. Anisa Liti, Prof. Dr. Margarita Hysko

In our study we have analyzed 1317 people, in the Microbiology Laboratory of DRSH, Durrës, Albania, suspected for C. albicans throat infections. Individuals we analysed were females and males, of different age groups, for the period of time between April 2012 and December 2013.

An Alternative to Direct Probe: Pyroprobe Coupled to High Resolution Time-of-Flight Mass Spectrometry
Jonathan D. Byer, Joe Binkley, Karen Sam, Jeff Patrick

Direct Pyroprobe is not a substitute for direct probe, but there is some overlap, as well as additional functionality. Direct probes coupled to LECO Pegasus instruments provide unique features:
– Time-of-flight mass spectra which shows little-to-no spectral skewing
– Automatic peak finding and spectral deconvolution for better identification
– Pegasus HT has a very low maintenance source which is beneficial for direct analysis techniques

A Reduced Workflow Solution for the Analysis of Gamma-Hydroxybutyrate (GHB) in Human Hair Samples Via an Automated Bead Mill as a Precursor to GCxGC-TOFMS and GC-HRT
Brittany M. Watt, David E. Alonso, Joe Binkley, Jeff Patrick, Frank A. Kero, Victor Vandell, Elena Gairloch, Brad Nolt, Tom Enzweller, Rhys Jones, Lee Williams, Karen S. Scott

- The Biotage Bead Ruptor 24 was effective in pre-treating hair samples prior to the extraction procedure.
- The enhanced chromatographic resolution of GCxGC-TOFMS and high resolving power of GC-HRT minimized interferences and facilitated accurate analysis of GHB in hair.

A FastGC Proton-Transfer-Reaction Quadrupole Ion Guide Time-of-Flight (PTR-QiTOF) Mass Spectrometer
Alfons Jordan1, Lukas Märk1, Jens Herbig1, Christian Lindinger1, Rene Gutmann1, Lukas Fischer1, Eugen Hartungen1, Simone Jürschik1, Gernot Hanel1, Philipp Sulzer1, Tilmann D. Märk1,2

In order to identify and quantify isomeric compounds independently in real-time, we introduce a novel approach where we integrate a fast GC column (“fastGC”) into a PTR-QiTOF instrument. The outstanding sensitivity of the new PTR-QiTOF (up to 4,700 cps/ppbv) is crucial for applications where time per analysis is limited, e.g. nosespace in food and flavor research. Particularly, in these fields the chemical environment is normally very complex so that a high selectivity is essential as well.

Integrating Fluorescent Carbon Nanodot Synthesis and Optical Detection of Methylmercury
Carlos Bendicho, Isabel Costas-Mora, Vanesa Romero, Isela Lavilla

In the last years, a great interest toward development of optical nanoprobes has arisen, so fluorescent nanomaterials have been implemented in analytical systems for the detection of several species. In this work, a novel assay that integrates the synthesis of fluorescent carbon dots (CDs) and sensing within one step, for the fast, sensitive and selective detection of methylmercury is presented.
