GC-MS (Gas chromatography – mass spectrometry)
- GC: Hewlett Packard 6890 series GC System with autosampler
- MSD: Agilent 5973 Mass Selective Detector (Electron Ionization MSD-EI, single quadrupole)
- Column: HP DB5 non-polar & several others capillary columns
GC-MS is the analysis method of choice for smaller and volatile molecules such as benzenes, alcohols and aromatics, and simple molecules such as steroids, fatty acids, and hormones. It can also be applied towards the study of liquid, gaseous and solid samples.
There are many advantages to using GC-MS for compound analysis, including its ability to separate complex mixtures, to quantify analytes, and to determine trace levels of organic contamination.
The Agilent 6890 is a leading GC system with state of the art dynamic temperature programming, EPC pneumatics and flow controls. The 6890 comes equipped with a split-splitless injection system that supports a wide variety of sample introduction techniques including thermal desorption, on-column injection, solid-phase micro-extraction (SPME), direct headspace injection, and solvent-based injections. Standard equipment includes a flame ionization detector (FID) ideal for running serial paraffins for retention index determinations. Read more

- Thermo ESI-MS DECA with quadrupole ion-trap MS/MS, MSn
The LCQ is an ion-trap based instrument normally fitted with an electrospray (ESI) ionization source (APCI is also available if required). It can operate in both positive and negative ion modes and is primarily used to analyse bio-molecules in solution such as proteins, peptides, biopolymers and oligonucleotides. The instrument is particularly useful for structural characterization of such species due to its ability to perform multiple stage (MSn) ion fragmentation analyses (up to 10 stages), allowing ion-mapping experiments to be conducted. It is also useful for analysis of high mass species that form multiply charged ions with ESI (such as proteins, peptides) due to the post-acquisition de-convolution capability of the operating software. It can be operated on a stand-alone basis with solution samples introduced by direct infusion using a syringe pump, or integrated with a Finnigan Surveyor LC system for LCMS applications.

- Thermo ESI-MS Advantage with ion-trap MS/MS, MSn
The Thermo Finnigan LCQ Advantage offers unmatched excellence in analytics when high levels of analytical specificity are needed to get the job done. An advanced analytical instrument. the LCQ Advantage includes a syringe pump, optional divert/inject valve, atmospheric pressure ionization (API) source, a mass spectrometer (MS) detector, and data system. The LCQ Advantage provides five levels of analysis for more positive compound identification: Chromatographic separation and compound; detection (retention time); Mass analysis (molecular weight information); Two-stage mass analysis (structural information); Wideband Activation (structural information); ZoomScan analysis (higher resolution scan). Wideband activation option adds energy during MS/MS fragmentation. ZoomScan analysis provides information about the charge state of one or more mass ions of interest.

- Perkin Elmer AAS
- Software AAnalyst 300
The AA-300 is used to determine the unknown concentration of an individual element by measuring the amount of light the unknown concentration absorbs. Instrument readouts are calibrated to display concentration directly. The basic instrumentation requires a primary light source, an atom source and a detector. The light source is a hollow cathode lamp (HCL) or electrode discharge lamp (EDL), which emits a spectrum specific to the element from which it is made. The light beam passes through either an air-acetylene or nitrous oxide-acetylene flame, which has a high temperature and specific flow rate. The atom source introduces the sample into the flame as an aerosol and the heat produces free analyte atoms. Analyte atoms in the flame that correspond to the lamp being used absorb energy from the light source. A detector, usually a photomultiplier tube, measures the light intensity exiting the flame. The electronics convert the amount of light absorbed to the actual sample concentration.
The AA-300 is equipped with an automatic six-lamp turret and is programmed to perform sequential multielement analysis. The AA-300 is equipped with lamps for the following elements: Ag, Al, As, Ba, Ca, Cd, Cr, Cu, Fe, K, Na, Mg, Ni, Pb and Zn The Iron(Fe) and Copper(Cu) lamps are the most commonly used.

Dionex Aquion Ion Chromatograph
Ion chromatography, a form of liquid chromatography, measures concentrations of ionic species by separating them based on their interaction with a resin. Ionic species separate differently depending on species type and size. Sample solutions pass through a pressurized chromatographic column where ions are absorbed by column constituents. As an ion extraction liquid, known as eluent, runs through the column, the absorbed ions begin separating from the column. The retention time of different species determines the ionic concentrations in the sample.
The Dionex Aquion Ion Chromatography System performs ion analyses using suppressed or non-suppressed conductivity detection. An ion chromatography system typically consists of a liquid eluent, a high-pressure pump, a sample injector, a guard and separator column, a chemical suppressor, a conductivity cell, and a data collection system. Before running a sample, the ion chromatography system is calibrated using a standard solution. By comparing the data obtained from a sample to that obtained from the known standard, sample ions can be identified and quantitated. The data collection system, typically a computer running chromatography software, produces a chromatogram (a plot of the detector output vs. time). The chromatography software converts each peak in the chromatogram to a sample concentration and produces a printout of the results.

Stereo Microscope Leica MZ-16A with camera (Leica Microsystems©, Wetzlar, Germany)
Stereo Microscope is designed for low magnification observation of samples, typically using light reflected from the surface of an object rather than transmitted through it. Stereo Microscopes provide the user with an upright and unreserved stereoscopic (3-dimensional) image. This is particularly useful for biologists or anyone who needs to work on small objects. The Stereo Microscope is often used to study the surfaces of solid dry or fresh parts or to carry out close work such as plants specific details, which are not easily visible. Features of these stereo microscope include resolution at 840 Lp/mm, highest magnification at 230x, motor zoom, automatic functions (measuring) and digital display. Objects in a magnification range from 7.1x up to 230x with a resolution of up to 840 Lp/mm can be scanned with objective nosepiece in the shortest amount of time.

Light Microscope Leica DM 1000 with camera (Leica Microsystems©, Wetzlar, Germany)
The optical, Light Microscope is a microscope that uses visible light and a system of lenses to magnify images of minute objects. Basic optical microscopes can be very simple, although many complex designs aim to improve resolution and sample contrast. The image from an optical microscope can be captured by normal, photosensitive cameras to generate a micrograph. Featuring high-quality optical performance, the Leica DM 1000 is ideal for biological laboratory applications, in particular cytology and anatomy. Its advanced capabilities includes height-adjustable focus knobs enhance operator comfort, fast changeover from right-to-left-handed operation, tubes with ergonomic viewing angle 15° or adjustable angle for optimal head posture and a straight back, Halogen 30W light illumination, etc.
