With the current world under crisis due to the SARS Coronavirus 2 (SARS CoV-2), which causes the disease known as COVID-19, people are searching for answers to their concerns. The Washington Post published an article at the '> of February providing details on the top internet searches related to COVID-19 (Ingraham, 2020). It’s no surprise the top search term was “Coronavirus.” People all over the world want to understand the details of this virus – what it is, how the virus is spread, and what the symptoms include.

Many of us have heard “wash your hands” time and time again. And while washing your hands is an essential part of personal hygiene, it is just one part of the solution in preventing the spread of COVID-19.

People are becoming more aware of the importance of regularly cleaning and disinfecting their work spaces, homes, and other areas that are defined as common spaces. While people are searching the symptoms, spread rate and other details about the virus, they are also searching terms like ‘Lysol’ and ‘Disinfectant.’

First off, cleaning and disinfecting are two different things, and not all household products are considered disinfectants – which means they are not considered affective against killing the coronavirus.

The CDC defines cleaning as, “the removal of germs, dirt, and impurities from surfaces,” (Cleaning, 2020). Cleaning does not kill germs, but rather removes germs from the surface. By removing from the surface, the spread rate and risk of infection decreases. On the other hand, the CDC defines disinfecting as, “using chemicals to kill germs on surfaces,” (Cleaning, 2020). Disinfecting surfaces does not necessarily clean dirty areas or remove germs, but rather kills germs on the surface, often cleaning a surface followed by disinfecting can be more effective. This also reduces the spread and infection rates.

While the two terms run hand-in-hand, not all household cleaning products are disinfectants – which means many cleaning supplies being used cannot kill coronaviruses. To find out which products are effective at disinfecting surfaces and combating COVID-19 you can view a list of registered products on the Environmental Protection Agency’s website.

As you search for cleaning supplies and disinfectants for your home, office and other common areas, take note of the low supply at your local grocery or convenient stores. The pandemic has sparked a lot of concern, which has led people to ‘stock up’ on various goods.

Companies are working as efficiently as possible to respond to the increasingly-high demands from public and private sectors needing supplies. The Clorox Company recently announced they are operating disinfection and cleaning production facilities 24/7 to help maximize supply (Dorer, 2020).

While this may seem like a shock to some, other companies are completely transforming business models to help combat COVID-19. Businesses who once manufactured beer, perfume, and other consumer goods are converting their manufacturing facilities to produce resources to combat the pandemic (Tognini, 2020). As production increases, throughput capabilities in quality control departments will also need to match pace.

If you reviewed the registered disinfectants, you may notice that many of them are recognizable products you currently use. You also may notice that many of them contain a compound called quaternary ammonium compounds. Actually over 60% of the registered disinfectants on the EPA website contain quaternary ammonium compounds.TitroLine 7500 Karl Fisher Titrator in Lab

Manufacturers who produce disinfectants with these compounds use titration as a means of quality control to ensure consistency in the production. Titration is commonly done manually using a simple glass burette set up. Though, with increasing throughput, the quantity of manual titrations would be nearly impossible for some companies, and would limit the throughput capability in laboratories. Employees will not only have to complete the titration by hand, but will also sp'> a significant amount of time monitoring the reactions.

Thankfully, there is equipment to avoid manually titrating samples. Automated titration equipment helps minimize the amount of time qualified employees sp'> on titrating samples. Xylem Lab Solutions offers a large portfolio of laboratory products that can be used in a variety of applications. YSI titrators are built to increase throughput capabilities, improve accuracy, repeatability, all while simultaneously keeping laboratory staff safe.
