Bringing Raman Spectroscopy to the Undergraduate Laboratory ............................................8
by B. Marquardt and G. Proskurowski A classroom-friendly device makes Raman more accessible.
Comparison of Crystallization Behavior of Different-Colored Polypropylene Parts Using a Single DSC Experiment................................................. 10
by J.A. Browne
On the Cover Shot in the Dark, captured by Rachel Garsed, 1st Prize in the ZEISS photography
competition 2015. This image shows what happens when a material is pushed beyond its limits: the strong electric field used to control the material has destroyed the liquid crystal, creating this pattern. The image provides valuable information about what conditions the liquid crystal can withstand, taking us one step closer to finding the ideal material. Image was taken between crossed polarizers.

The crystallization characteristics of different-colored polypropylene marker caps are compared.
Proper Monitoring of Refrigerators and Freezers to Protect Valuable Biomedical Inventory .................... 14
by R. Fusco Understanding cold storage best practices can help laboratory managers ensure that their medical inventory is in compliance and that they have the documentation to prove it.
High-Throughput VOC and Inorganic Gas Analysis: Automated SIFT-MS ..................................................... 17
by M.J. Perkins, V.S. Langford and M.J. McEwan
ULTRA PRECISE PIEZO-Z FOCUSING STAGE
Selected ion flow tube-mass spectrometry (SIFT-MS) provides unique opportunities for high-throughput sample analysis.
APPLIED SCIENTIFIC INSTRUMENTATION
Compact HPLC Systems for the Analysis of Pesticides, Dyes and Drugs ........................................... 26
by V. Orlovsky, T. Sgibnev and K. Tchalukov Novel HPLC systems are used in a variety of pharmaceutical, agricultural and consumer applications.
The Growth of Mass Spectrometry in the Clinic .............. 30
by L. Thomas and B. Hart Researchers are pushing the boundaries of MS, driven by advances in the technology.
The Ultra Precise Piezo-Z Stage is a perfect solution for your super resolution microscopy applications. The stage is capable of XY resolutions down to the 10-20 nm range and Z resolutions to the 1nm range. It is also capable for use with rapid z-sectioning and autofocus systems. It prevents focus drift when used with our CRISP system.
