Molecule 2017

Can you guess what protein serves as this year’s Quantum Northwest “Molecule”?

This year’s Molecule

Quantum Northwest serves a variety of forms of spectroscopy, including pulsed-laser photoacoustic spectroscopy (PAS).  In PAS, the energy of a laser pulse is absorbed by a molecule in solution.  Part or all of the absorbed energy is released as heat, generating a rapid expansion of the solution around the molecule.  This expansion causes an ultrasonic acoustic wave to be generated… hence, “We torture molecules with light and listen to them scream.”  The screams may be detected using an ultrasonic transducer clamped to the side of the cuvette.  Read more about PAS here.

Next year

Next year’s Biophysical Society Meeting will be held February 17-21, 2018, in San Francisco, California.

Have fun while you are in New Orleans

Make sure you see the highlights of New Orleans while you are in town! The city offers many different sightseeing destinations, activities and experiences.

Frenchman Street

Address: Frenchmen Street, New Orleans, LA
Frenchmen Street is a four-block stretch of live music, bars, restaurants, nightclubs and art galleries. Here, not only will you find fewer crowds, but you’ll also encounter cheaper eats and drinks, and better music. And if you’re not into nightlife that’s OK, too, because the Frenchmen Art Market (open daily 7 p.m. to 1 a.m.) is a shopping haven where locals sell homemade art and jewelry.

French Quarter (Jackson Square, St. Louis Cathedral, the Faulkner House and the Cabildo)

Address: Canal St to Esplanade Ave, Mississippi River to N Rampart St, New Orleans, LA

The neighborhood, also known as Vieux Carré, is the heart and soul of this city, and it’s also a National Historic Landmark. As the site of the original New Orleans colony (established by the French in 1718), the French Quarter has held on to its heritage, complete with street names that are still listed in French. Wander the narrow cobblestone streets to find such attractions as Jackson Square, St. Louis Cathedral, the Faulkner House and the Cabildo. While you’re strolling, pay attention to the neighborhood’s architecture: balconies are designed with baroque ironwork and hanging plants, while leafy courtyards are filled with bubbling fountains.

Saying goodbye to summer

Thanks to our customers around the world, we at Quantum Northwest have stayed busy this summer!  Orders have come in, devices have been manufactured, and final products have been neatly packaged and shipped to destinations around the globe.

Summer in the Inland Northwest

We keep the doors open (literally) on nice summer ­days at our facility in Liberty Lake, Washington.  Among our visitors this summer have been a wild turkey who sometimes checks us out in the mornings, and a praying mantis (named “Harold”) that has chosen to take up residence in our manufacturing area.  Fortunately for Harold, we are providing him with elegant shelter and ample food, and a mantis-eyed view of new instruments being made.

How far, how fast, and how steep: specifications and ramping

Quantum Northwest manufactures Peltier-based cuvette holders for almost every form of optical spectroscopy. In fact, we offer the largest selection on Earth. To illustrate the capabilities of our products, we have posted brochures on the specifications and ramping features of our products.

Specifications

Take a look at our specifications table to learn about the things we build into each and every cuvette holder we make. These include magnetic stirring to rapidly unify sample temperature, dry gas purge to eliminate condensation on cuvette surfaces at cold temperatures, and the ability to accept a thermistor probe to independently measure the sample holder temperature. Each cuvette holder may be linearly ramped, so that the temperature is varied at a constant number of degrees Celsius per minute, controlled by the user. Ramping is explained in further detail below.
Quantum Northwest products vary in the number of optical ports per cuvette (2, 3 or 4), the number of temperature-controlled cuvettes in the cuvette holder (1, 2, 4 or 6), and the temperature ranges offered in each device, with the maximum range offered at -55 to +150 degrees Celsius.

Ramping

The guide to ramping for Quantum Northwest products describes three general ways you can precisely vary the temperature of the sample in a linear manner. Ideally, the same software you use to control your spectrometer, setting the wavelengths used and measuring absorbance or fluorescence, for example, would also control the temperature of the sample and report all data to a single file. Many manufacturers offer this feature, including Applied Photophysics, Edinburgh Instruments, PicoQuant, and Horiba PTI.
For Agilent and Shimadzu spectrometers, software solutions for control and ramping exist, as described in the guide. However, it is also possible to control ramping independently of the spectrometer operations. This can be done by manually pressing buttons on the front panel of the TC 1 Temperature Controller, or by using Quantum Northwest’s software, T-App or Q-Blue.

Help with specifications and ramping

If you have questions on specifications and ramping, please contact us.

Quantum Northwest at Analytica 2016, Munich

Munich, Germany was the site of the Analytica 2016 International Trade Fair for Laboratory Technology, Analysis, and Biotechnology. Quantum Northwest’s President, Dr. Enoch Small, demonstrated the application of Peltier-controlled cuvette holders for a variety of forms of spectroscopy serving analytical measurements.

Analytical measurements are better with temperature control

Critical to many spectroscopic measurements is the temperature at which the measurement is made. Quantum Northwest offers almost 100 different Peltier-based, temperature-controlled cuvette holders that fit in a variety of destination spectrometers. Several spectrometer companies install Quantum Northwest cuvette holders into their instruments at the time of sale, but it is possible to buy a cuvette holder for a new or used spectrometer, thus upcycling the spectrometer and maximizing its performance for analytical measurements.

Upcycling with the t2 Sport for improved analytical measurements

Upcycling old spectrometers for quality analytical measurements

Currently popular is the Quantum Northwest t2 Sport temperature-controlled cuvette holder, which fits many instruments, including the Agilent 8452, 8453, and 8454 UV-Vis diode array spectrophotometers. For quality analytical science, the inexpensive t2 Sport provides temperature control from -15 °C to +110 °C with a precision of ±0.02 °C.

Many analytical measurements require multiple samples run at the same time, at the same temperature, with the same magnetic stirring of samples. The new Shimadzu RF-6000 spectrofluorophotometer is used for analytical measurements such as fluorescence, bioluminescence, chemiluminescence, and electro-luminescence measurements. The QNW Peltier is engineered to fit in the destination spectrometerAdding a Quantum Northwest Turret 4 to the Shimadzu RF-6000 is easy: Quantum Northwest has designed the hardware needed to drop the Turret 4 into the Shimadzu RF-6000 once the original sample chamber has been removed.

Analytical measurements for all forms of optical spectroscopy

Quantum Northwest’s expertise in designing temperature-controlled cuvette holders makes it possible for accurate and precise analytical measurements for all forms of optical spectroscopy.

Mountain Photonics, the distributor for Quantum Northwest products in Germany, Austria and Switzerland, was the host for Quantum Northwest’s display at Analytica 2016.

OLIS leads the way in upcycling

OLIS has shown the way on how to upcycle an existing spectrometer in your laboratory in order to reduce waste.  The concept of upcycling – one step better than recycling – means that you can take an older instrument with excellent optics and improve its electronics and cuvette handling as needed.

Upcycle with Quantum Northwest

Quantum Northwest offers Peltier-based cuvette holders that work in the spectrometers of 21 different manufacturers, from Agilent to Thermo Fisher!  Whether your spectrometer is still-in-the-box new, or the old unit in the back of your laboratory, you have the option of getting the temperature control and magnetic stirring you need for high quality work.  Upcycling works.

As an example, check out the multi-position qCHANGER 6 in the video below.

The qCHANGER 6 is easily inserted into the Shimadzu UV-1800 spectrophotometer.  Simply pull out the existing sample compartment, put in the qCHANGER 6 (complete with the needed hardware), turn on the TC 1 controller, and get ready to do high throughput spectroscopic measurements.

Quantum Northwest’s website lists products for common spectrometers.  If you don’t see yours listed, just contact us.  We’ll guide you to the upcycling options that will work best for you.

When you drill down to see our products for use in fluorometers, for example, you’ll see the same product in different formats, each customized to drop into a specific instrument.  The added hardware (baseplates, front panels, and the like) makes your job easy.  So the Luma 40 product family shown below, for example, looks diverse, precisely because Quantum Northwest has worked out the details of easy replacement of the spectrometer’s existing sample compartment with a new Peltier-based cuvette holder.
