Calibration of the Variable Temperature NMR Thermocouple
The variable temperature (VT) unit on our machine uses a thermocouple wire to measure the temperature of “the sample.” However, because the thermocouple wire does not physically touch the sample…
Chemistry Video: EP’s NMR services
NMR capabilities extend well beyond the 1-dimensional 1H NMR spectra that organic chemists typically acquire. We strive to educate organic chemists on the techniques that can help them obtain the…
Testing Antimicrobial Activity and Cytotoxicity of Wound and Skin Cleansers
Chronic non-healing wounds, such as venous ulcers, diabetic ulcers, and pressure ulcers cause tremendous patient suffering. Treatment of such wounds presents a serious unmet medical need. Strategies that optimize the…
Screening for Inhibitors of Bacterial Multidrug Efflux Pumps
Microbial resistance to drug therapy is an area of increasing concern (https://www.cdc.gov/drugresistance/). The emergence of drug resistance in microorganisms can occur by several different mechanisms (Debabov, 2013), one particular mechanism…
Quantitation of Polysorbate 80 in a Commercial Product
Contact the Author Polysorbate 80 is a surfactant and emulsifier frequently found in foods, drug products, as well as in biochemical solutions and preparations. Although its presence in foods is…
EP offers Quantitative Biofilm Models for Today’s Research Needs
Microbiology Services – Quantitative Biofilm Service Assay Microbial biofilms are everywhere. Biofilm formation occurs when planktonic cells (bacteria, yeast, fungi, etc) attach and colonize living or non-living surfaces. Plaque on…
Diffusion-Ordered Spectroscopy (DOSY)
Contact the Author Diffusion-Ordered SpectroscopY (DOSY) is a technique in which a mixture of signals from a mixture of compounds can be separated on the basis of their diffusion coefficients. …
Assignment of Complex NMR Spectra
Do you have a need for NMR services beyond basic 1-D proton spectra? Do you need expertise in analyzing and interpreting NMR data for discussions or presentations or publications? We can help by…
The Global Importance of Emery Pharma’s Microbial Analysis
Antibiotic resistance is a growing worldwide public health crisis. Resistance is emerging faster than modern science is able to replace the armamentarium of effective antimicrobial agents. Currently, over half of Staphylococcus aureus…
