Adding More Automation and Raising Accuracy
In many research and commercial processes, a scientist measures a sample’s concentration of something, from the oxygen concentration in water to the vitamin C in food. Making those measurements requires titration.
Controls make up some of the most obvious advances in titrators. “The technology is keeping up with others in terms of interfaces,” says Mari Lynne Gentry, product manager for instruments at METTLER TOLEDO (Columbus, OH). That includes the use of software apps and a touchscreen in many cases.
Every chemist, or even chemistry student, once performed titrations manually. For instance, Gentry says, “Universities often teach the manual process, and some small wineries use it too.”
Nonetheless, more users now look for automatic options. “There’s an evolution in customers moving to automatic titrators as a more efficient and effective way of getting reproducible and accurate results,” says David Minsk, president at Hanna Instruments (Smithfield, RI).
