Quality control of disinfectants during production

  • Application description
  • FT-IR spectroscopy
  • Raman spectroscopy

Since 2002, the US CDC has also recommended alcohol-based products for hand disinfection: isopropanol, ethanol, n-propanol, or a combination of two. The antimicrobial activity of these alcohols is attributed to their ability to denature proteins. The best antimicrobial efficacy can be achieved with ethanol (60 to 85%) and isopropanol (60 to 80%), but higher concentrations are less effective because proteins are not so easily denatured in the absence of water.

In response to the Covid-19 pandemic, a number of countries have allowed the temporary use of unapproved disinfectants, which has not only provided new opportunities for their suppliers, but also posed new challenges in the form of the need for reliable production control.

Because it is necessary to ensure fluency and disrupt as few processes as possible during production, it is suitable to take advantage of the properties of molecular spectroscopy: the speed of measurement and the need for no or minimal sample treatment. When using the ATRtechnique, all you have to do is apply a small amount of sample to the crystal and you will get an easily interpretable spectrum in a few seconds.

Intelligent software

The trouble-free operation of FT-IR spectrometers is ensured by the OMNIC control program. In the case of the Nicolet Summit device, it is the OMNIC Paradigm, in which it is possible to easily create workflows that will make your work even easier.

In addition, it is possible to develop customized calibration methods in the TQ Analyst program, so you will get not only the spectrum of the sample, but also the data on the concentrations of the monitored substances in a few moments.

Nicolet Summit is a small, easy-to-operate, reliable and low-maintenance infrared spectrometer that makes infrared spectroscopy accessible to all users, not just spectroscopic professionals. The high reliability of the individual components of the device makes it almost indestructible and significantly reduces operating costs.
Nicolet iS5 = Portability + precise scientific measurement parameters The Nicolet iS5 FT-IR spectrometer is a small, easy-to-operate, reliable and low-maintenance infrared spectrometer that makes FT-IR spectroscopy accessible to all users, not just spectroscopic professionals. The high reliability of the individual components of the device makes it almost indestructible and significantly reduces the cost of its operation.
In the last decade, thousands and thousands of users have set the Nicolet iS10 FTIR spectrometer as the new, high standard for laboratory infrared spectrometers. Now its successor, the Nicolet iS20 FTIR spectrometer, is raising the innovative bar to the next level!
The Nicolet iS50is the first scientific one-touch FT-IR spectrometer. Based on extensive experience with previous successful Magna, Nexus and Nicolet X700 scientific systems, a new FT-IR spectrometer has been developed which, thanks to a wide range of measuring accessories and interconnected analytical software, delivers a universal material analysis system with unrivaled ease of use.
Disperzní Ramanův spektrometr Nicolet DXR3 SmartRaman je přístroj určený pro všechny aplikace vyžadující jednoduchost přípravy vzorků a využití všech silných stránek Ramanovy spektroskopie.
The portable (handheld) Raman spectrometer TacticID-1064 is an ideal tool for fast and non-contact forensic analysis. This allows the measurement of samples with strong fluorescence (e.g. street drugs).
Thanks to the integrated touch screen, the i-Raman Pro can also be used without an external PC or laptop.
