Why don't NSGs calibration standards require re-calibration?
Farmingdale, NY (PRWEB) August 27, 2013
NSG Precision Cells is becoming the number one manufacturer of spectrophotometer calibration standards in the world. Since the release of their calibration standards line back in 2010, NSG is getting more and more customer every day.
Many customers come to NSG because they know they can benefit from the yearly savings by investing in an NSG solid-state calibration standard. The savings result from the fact that NSGs standards never need to be re-calibrated. But what is it about these standard reference materials that make it so they never need re-calibration? The answer is "Nano-Deposition Layering (NDL)."
Nano-Deposition Layering is a series of special optical coatings that is applied to the glass material. This coating traps the original properties of the glass. It is like putting a cage around the original material so it cannot escape. This results in the fact that it is impossible for the material to degrade over time.
In NSG's ISO/IEC 17025 accredited lab they perform every step of the NDL process. First the standard reference materials are cleaned and polished to the proper specificiations. After cleaning the plates are ready to be coated. Each Nano-layer is carefully applied by hand by a certified optical engineer. Once the layer sets the next step is to apply a few additional coats to ensure a perfect seal. After all the coatings are applied, now it is time for the plates to be cut.
After cutting, the plates are placed into their black aluminum holder. Each calibration filter is scanned multiply times on a calibration grade Perkin Elmer spectrophotometer. Once the scanning is complete, the Nano-Depositioned Layered standards are sent to be checked under a microscope to ensure that the layers are absolutely perfect.
People who bought these standard reference materials in 2010 have been reaping the benefits of having the calibration standards always on hand. Not to mention the savings of over $300-$1,000 per year in re-calibration fees.
It's a complete shock when people ask NSG sales reps for re-calibration fees and they hear "Well our standards never require re-calibration." The silence on the other end of the phone says it all. Then the next question comes, "Why don't NSGs calibration standards require re-calibration?" NSG then explains the details about the NDL process and the decision becomes a no-brainer.
NSG has a complete line of standard reference materials that have NDL technology. These calibration standards range from UV-VIS photometric accuracy, wavelength standards, VIS photometric accuracy, and stray light. Additionally, NSG is the only company that has dual purpose calibration filters.
NSG makes it very easy to purchase their NDL standard reference materials. Scientists can log onto the NSG homepage or Amazon.com to buy the filters directly on-line. NSG keeps all their NDL filters in stock so once the order is placed NSG ships the order the same day.
Given all the benefits of Nano-Depostion Layering and NSGs customer service, it is clear why more and more scientists are coming to NSG for their calibration needs. Scientists who have not upgraded need to take action now to rid their labs of those old liquid calibration standards that needlessly waste yearly grant money.
