Tekmar Talk Blog

With today’s blog, let’s get to know the employees of Teledyne Tekmar. The next person I would like to introduce you to is Amy Nutter.

Amy is the VOC Technical Product Specialist at Teledyne Tekmar. Currently, she is focused on fostering relationships with OEM partners by developing applications and webinars for the Purge and Trap product line. She also provides customer application support. Amy has been with Teledyne Tekmar for 5 years. She was previously the VOC Applications Chemist for the Purge and Trap product line.

Let’s ask Amy some questions to get to know her better.

With today’s blog, I thought maybe we could go down another direction and get to know the employees of Teledyne Tekmar/Leeman Labs. The first person I would like to introduce you to is Tyler Trent.

Tyler is the Elemental Product Marketing Manager for Teledyne Tekmar and Leeman Labs. He oversees the TOC, ICP and Hg product lines. Tyler is entering his 12^th year at Teledyne. Over the 12 years he has cover a wide range of roles.

Tyler was hired right out of college and has held the following positions: Application Chemist, Application Sales Specialist, Europe Middle East, and Africa Sales Manager and now his most recent role of Elemental Product Marketing Manager.

Let’s ask Tyler some questions to get to know him better.

Pharmaceutical production entails strict quality control and precise analytical testing methods. The United States Pharmacopeia (USP), European Pharmacopeia (EP) and Japanese Pharmacopeia (JP) have promoted TOC analysis as the analytical technique to verify that cleaning validation, purified water (PW) and water for intravenous injection (WFI) meet the high standards of the pharmaceutical industry.

Total Organic Carbon (TOC) is defined as the amount of carbon bound in an organic compound and is often used as a non-specific indicator of water quality or cleanliness of pharmaceutical manufacturing equipment.

Hello all,

For those of you who are reading this from your office, or laboratory, please do be safe and thank you for the essential functions that you continue to serve, despite the risk to you and your family. We are all grateful for your efforts. However, if you’re like me right now, you are reading this from home. While it is certainly an adjustment (how is it possible that two toddlers can sound like a herd of elephants migrating through a bubble wrap factory!?), it is very important for those of us who can, to stay home and slow the spread of COVID-19. All the same, it is probably difficult being away from your instruments, even if this is a good time to catch up on other tasks. When all of this comes to an end, and eventually we return to work, in what kind of condition will we find our instruments?

Bees are in trouble. Managed bee colonies in the United States have decreased from 6 million in 1947 to 2.5 million in 2016. This is more than a simple threat to the honey supply. Bees are crucial to food supply, and in fact, one-third of what we eat comes form insect-pollinated plants. The honeybee is responsible for 80 percent of that pollination.

Understanding the impact of pesticides has become a major fight of the Environmental Protection Agency, which recently found that “A major pesticide harms honeybees when used on cotton and citrus, but not on other crops like corn, berries and tobacco.”

The EPA completed the first scientific risk assessment of the neonicotinoids, a class of pesticides debated by scientists, environmentalists and beekeepers. This is the first of four risk reports for this class of chemicals, which include neonicotinoids, clothianidin, thiamethoxam, and dinotefuran. This is also the first

 time the EPA has actually acknowledged that a major pesticide is killing bees. Anti-pesticide groups want to ban the pesticides, which works on the central nervous systems of insects. Europe banned neonics, but then lifted the ban.

The Environmental Working Group published its annual Dirty Dozen list of the 12 fruits and vegetables with the highest pesticide residue. Topping the list the last five year were apples, but this year, strawberries were the most contaminated.

According to an EWG news release about the 2016 Shopper’s Guide to Pesticides in Produce, “Nearly all strawberry samples - 98 percent - tested by federal officials had detectable pesticide residues. Forty percent had residues of 10 or more pesticides and some had residues of 17 different pesticides. Some of the chemicals detected on strawberries are relatively benign, but others are linked to cancer, reproductive and developmental damage, hormone disruption and neurological problems.

“Strawberries were once a seasonal, limited crop, but heavy use of pesticides has increased yield and stretched the growing season. In California, where most U.S. strawberries are grown, each acre is treated with an astonishing 300 pounds of pesticides. More than 60 pounds are conventional chemicals that may leave post-harvest residues but most are fumigants - volatile poison gases that can drift into nearby schools and neighborhoods.”

Teledyne Tekmar recently released a new guide that compares Total Organic Carbon analysis techniques. The guide provides important details for users and recommends the best instrument for your specific application. TOC analysis, which is used in a variety of labs, is a technique employed to determine water cleanliness and purity. It is a required test by the United States Pharmacopoeia (USP), European Pharmacopoeia (EP) and Japanese Pharmacopoeia (JP), and is frequently used to monitor wastewater, soils and drinking water safety.

Total Organic Carbon (TOC) analysis is a process used by environmental, pharmaceutical, university and petrochemical labs to determine water cleanliness and purity. It is required analysis by international pharmacopoeia for water, wastewater and soils applications. It is also starting to find traction in other industries such as cosmetics, even though there is not a regulatory requirement to use the technique.

An article written by Ben Dingwall, a business manager at TRB Chemedica, cites the focus on quality and safety within the cosmetics industry as the reason why TOC is being used more frequently. Adoption of this purification technique is driven by a number of cosmetics companies that are “aligning the process with Current Good Manufacturing Practices (cGMP).” These best practices help companies meet established guidelines recommended by agencies that authorize and license them to manufacture and sell cosmetics.

Roughly 30 percent of the world’s helium supplies comes from Qatar. Earlier this year, a blockade of Qatar by surround countries cut Qatar’s main route out of the country when Saudi Arabia and several other countries in the Middle East cut diplomatic ties with Qatar over concerns about Iran and extremists.

As a result of the blockade, experts were estimating another round of shortages and dramatic price increases for scientific instrument users. To offset the potential challenges of reduced supply coming from the region, U.S. Bureau of Land Management (BLM), which accounts for about 20% of global helium supply, ramped up production during the summer at its Cliffside facility in Texas. For the past several decades, the U.S. reserves in Texas have been the main source of helium worldwide. By 2021, commercial supplies of the gas at that location will end.
