Varian 500-MS Ion Trap
Enhanced Charge Capacity provides the 500-MS LC with the capability to detect trace amounts in a high concentration of coeluting analytes in heavy matrices. Temperature programmable SelecTemp™ API interface reduces contamination. Unidirectional triple resonance scan method preferentially ejects trapped ions toward the detector. TurboDDS™ Data dependent scanning option allows MSn for automated qualitative analysis. Varian’s Mass ID™ deconvolution software aids in the molecular weight determination of large molecules that are detected as multiply-charged ions, such as proteins, peptides and oligonucleotides. The Varian 500-MS LC Ion Trap is the instrument of choice for high-throughput LC/MS analysis where sensitivity, reliability and productivity are essential. Sensitivity enhancements include SelecTemp™, the unique temperature programmable API (Atmospheric Pressure Ionization), enabling optimal analysis of thermally labile compounds. All of these technical capabilities lead to the remarkable performance and productivity delivered by the Varian 500-MS LC ion trap. SelecTemp’s programmable temperature control delivers optimum drying gas temperatures at every time point throughout a complex analysis. Additional SelecTemp API benefits include reduced interface contamination, improved throughput, simplified setup and easily recordable parameters for GLP purposes. Premium scanning and the power of MSn Achieve unit mass resolution with uncompromised qualitative and quantitative results for narrow or coeluting chromatographic peaks at scan speeds of up to 15,000 Da/sec with the patented ‘unidirectional triple resonance’ scan method that preferentially ejects all the trapped ions toward the detector. The fast scan speed is complemented by rapid ion polarity switching of 200 milliseconds to accommodate the optimum detection of ion polarity for every analyte in the sample. Enhanced qualitative information is delivered by the 500-MS with MSn operation to n=10, expanding the spectral information content for structure elucidation.

Model: Micromax/Micromax RF
The IEC Micromax/Micromax RF delivers superior separating power in less time. Micromax reaches forces up to 21,000 xg at speeds of 15,000 rpm on 24 (1.5-2.0 mL) samples or 48 (0.5 mL) microtubes in less than 15 seconds.
More Separating Power and Less Maintenance The IEC Micromax/MicromaxRF microcentrifuge produces forces up to 21,000 xg at speeds of 15,000 rpm on 24 (1.5-2.0 mL) samples or 48 (0.5 mL) microtubes. IEC Micromax's brushless motor is designed for longevity and requires no maintenance. All controls are microprocessor based for added reliability.
More Flexibility and More Convenience The IEC Micromax includes a choice of g-force or rpm speed control, gentle and fast acceleration and braking rates, audible end of run signal, as well as momentary spin and time hold selections. A "glove friendly" membrane control panel with digital display makes it easy to clean and to operate. Repeat runs are as simple as touching a single membrane switch.
Less Noise, Less Space and Less Time Other less powerful microcentrifuges are noisy distractions, but the IEC Micromax operates at a quiet 55 BA at full speed, so you can work while Micromax works. Only 12 inches wide, this machine requires less bench space than the majority of microcentrifuges (particularly refrigerated) with comparable sample capacity and power. It takes less than 15 seconds to attain 21,000 xg or to brake allowing you to process more samples per day.
Unique Polypropylene Microtube Rotors Virtually impervious to chemical attack and may be repeatedly autoclaved without damage. New sealed rotor provides aerosol containment, and can be removed from the Micromax (seal intact) and opened under an environmental hood.

Perkin Elmer Auto-system XL
Gas Chromatograph
This Perkin-Elmer Autosystem XL gas chromatograph has PE-5 capillary column installed with a split/splitless injector and one detector-FID.
The gas chromatograph is employed to study the composition of volatile substances such as solvent mixtures. It is used for the quality control both of raw materials and of finished products. The vapours of the solvent mixture are forced to pass through a very thin tube usually 30 meters long (called column); they are transported by a constant flux of an inactive gas, usually nitrogen. The sides of the tube are covered with a particular substance. Different solvents have different degrees of " attraction " towards the substance that covers the sides of the tube. So the solvents more "attracted" to the tube will be moving at a slower pace, whereas those that have less attraction will be the first ones to exit the tube. A detector placed at the end of the tube calculates the time necessary for every solvent exit. Every solvent has its constant time characteristic. Therefore, it is possible to identify the solvent according to the time it needs to exit the tube.

Zetasizer Nano Series Dynamic Light Scattering Detector
The new Zetasizer Nano series is ideal for protein characterization. The user friendly software includes customizable protein specific reports, a solvent builder library, and protein utilities to assist with the interpretation of data. The new technology incorporated in these systems delivers unequalled sensitivity and versatility. Protein size NIBS/DLS technology enables measurements of protein molecules down to 0.3nm hydrodynamic radius (equivalent to less than 1 kDa). Highest sensitivity - 0.1 mg/ml Lysozyme, for larger molecules even lower concentrations can be detected. Low sample volume - only 12µl sample volume are required and hence only small amounts of protein, and the sample can be recovered. Precision temperature control Peltier elements provide software controlled temperature range from 2°C to 90°C for accurate temperature scans.
Absolute molecular weight - An avalanche-photodiode detector and fiber detection optics give the sensitivity and stability required for absolute molecular weight measurement. The Zetasizer Nano S provides a powerful, easy to use protein characterization tool for every laboratory. All systems are compatible with the MPT-2 autotitrator to enable trend measurements and sample preparation to be automated. In principle, any small ˜particle™ can be measured using DLS - if sufficient light is detected and the particles are diffusing freely. For sub-nanometer particles, however, the level of scattered light, even at high concentrations is usually so small that only the most sensitive experimental setup can detect them. In this application note cholesterol (MW 387Da) in butanone, is prepared at 20 mg/mL. The hydrodynamic radius is found to be 0.3nm, or 3 Angstroms. This value agrees with expectations for this molecular weight range.

Mocon Ox-Tran Model 2/21 Oxygen Permeability
The Barrier Properties laboratory utilizes gas and vapor transmission measurements, as well as thickness measurements to calculate permeation rates through various materials. Flat films, flexible packages, and non-flexible packages can be evaluated by any of the following techniques:
Oxygen Transmission Rate (O2TR) Testing can be performed on flat films, as well as flexible and rigid packages. Testing may be conducted under a range of relative humidity conditions at a range of temperatures. One side of the film is exposed to the oxygen permeant. As it solubilizes into the film and permeates through the sample material, nitrogen sweeps the opposite side of the film and transports the transmitted oxygen molecules to the coulometric sensor. This value is reported as a transmission rate. When this rate is multiplied by the average thickness of the material, the results are considered a permeability rate. Typical applications might include packaging for the beverage and fresh food storage industry, as well as pharmaceutical packaging.
