Microtrac provides sample introduction flexibility with the release of the Nanotrac Wave II

Microtrac, the global pioneer of particle characterization solutions is thrilled to announce the release of the Nanotrac Wave II Dynamic Light Scattering analyzer. Ideal for colloids ranging in size from 0.3 nanometers to 10 microns, the Nanotrac Wave II delivers superior accuracy and sensitivity across a wide concentration wide.

Designed to meet the growing customer demand for sample introduction flexibility, the Nanotrac Wave II can be configured with one of the following: a removable Teflon or stainless steel sample cell, disposable plastic or glass cuvette, or an external probe for in-situ analysis. Sample volumes range from 50 µl microcuvettes to 3 ml cells making the Nanotrac Wave II one of the most versatile DLS analyzers on the market.

“When selecting a tool… you want the right one for the job,” says Paul Cloake, President of Microtrac. “We believe that the ‘one size fits all’ approach for sample introduction is wrong because each customer has unique processes and needs. Rather than forcing you to change your process for a tool, we provide an adaptable tool, which delivers a better customer experience, and most importantly, accurate results.”

Whether measuring at ppb or near finished product, the Nanotrac Wave II utilizes Microtrac’s proprietary Reference Beating, an enhanced optical signal that enables precise analysis capability of monodispersed and polydispersed samples. Applications that are routinely characterized with the analyzer include inks, pharmaceutical ingredients, proteins, and chemicals like silica (to name a few).

“Since the launch of our first DLS over 25 years ago, we have continually refined our technology and improved our particle sizing and zeta potential analysis capability with each release, said Dr. Paul Freud, Microtrac’s Senior Research Scientist. “That commitment to quality translates to better performance compared to other DLS systems on the market. As we gain new customers, our team never gets tired of hearing ‘I didn’t realize your DLS could provide me with data that accurate.”

Interested parties who are searching for a sensitive and precise DLS particle analyzer are encouraged to submit samples for a complimentary analysis. Click here to speak with a technical specialist today.

Using Particle Charge Titration to Understand Eggnog

Posted on: December 13th, 2013 by Microtrac 2 Comments

With Christmas rapidly approaching, Jesse has been working hard on a variety of projects to help support the lab.  Today we found Jesse with an opened container of eggnog.  We began to wonder if the job became too stressful, or Jesse wanted to get a jumpstart on the holiday celebration.

As it turns out, Santa is a big fan of eggnog and only drinks the best.  But Santa has to be careful, because too much eggnog could upset his stomach.   His love of eggnog sounds awfully similar to his obsession with fine gingerbread cookies.

Eggnog is an emulsion and understanding the stability of the mixture is vital to determining its quality and maintaining the right taste.  The slightest deviation in pH could affect the entire batch and have a negative outcome on the taste.  The proper pH balance is important, especially if you are adding alcohol to the eggnog.  Too much alcohol, and the eggnog will chemically turn into an unstable mess, and no one wants to deal with that kind of mess around the holidays.

Santa has asked Jesse to run a titration experiment on a new brand of eggnog to make sure it’s up to his standards.  He wants to know chemically, what is the perfect amount of alcohol that he can add to his eggnog to make sure it does not upset his stomach, and taste great.

Santa is all about speed, how else could he deliver that many toys in one night? Santa asked Jesse to run the experiment on theMicrotrac Stabino, which conducts a forward titration in 5 minutes! That’s roughly an average timesaving’s of 85 minutes.  Talk about fast!

Jesse measured 300 ml’s of eggnog and kept adding various amounts of alcohol in hopes of finding the “right mix.”  Jesse was able to determine that 60 ml  (approximately two shots – depending on who’s pouring) of alcohol was all that was needed to reach the isoelectric point at 3.4.  

Now that Santa knows what it takes to make his eggnog perfect from a chemical standpoint, he is ready to go for the Holidays.  I wonder what he will ask Jesse to do next.  Stay tuned!

 

We apologize for an inaccuracy in this post.  Please click here to set the record straight!
