2015 TOC Analyzer Survey Results

Total Organic Carbon (TOC) analyzers are a mainstay of environmental and quality control chemistry. TOC, a crucial metric in many processes, may arise from a combination of living or dead organisms or chemical contamination. Its measurement can serve as a surrogate for more difficult measurements or a screen for further analysis.

Millennials in the Lab

Ducks and water. Birds and sky. Squirrels and trees. Some things just fit their environments perfectly. Similarly, with their technological savvy, millennials could be considered the perfect fit for the laboratory, according to the lab managers we spoke with.

INSIGHTS on Big Data in Drug Discovery

Big data might bring more benefits to drug discovery than to any other field. For one thing, discovering a new drug turns out to be incredibly difficult. On average, a pharmaceutical company tries about 10,000 drug candidates for every one that ends up on the market. Plus, the process of discovering and developing a new drug costs hundreds of millions of dollars and takes more than a decade—some say more for both measurements.
