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.

Top 5 Questions You Should Ask When Buying a TOC Analyzer

  1. Is the TOC technology suitable for your specific application or water conditions? Many TOC technologies may be suitable only for waters with a narrow range of organic or inorganic contaminants.
  2. Are different models available to meet your current and future sampling needs (i.e. online, portable, laboratory)? Do these models use similar technology to simplify method transfer or data comparability from lab to online?
  3. Does the company offer the documentation and support necessary to help meet applicable industry or government regulations?
  4. What is the company’s level of experience supporting sales of TOC analyzers in your specific industry? Do they understand the unique challenges specific to your application?
  5. What type of service, applications, and technical support are available during and after the purchasing process?

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.
