Utility & Versatility: 6 Surprising, Innovative Uses of FTIR Analysis


Uses of FTIR Testing & AnalysisFourier transform infrared spectroscopy (FTIR) has origins that date all the way back to the early 19th Century, when Sir William Herschel first developed prism-based techniques for measuring IR spectra. Today, FTIR testing and analysis has become go-to quality assurance measure for manufacturers, as well as a scientific tool for everything from crime scene investigation to identifying gemstones.

Why? Because FTIR testing can determine a sample’s molecular composition and structure, making it a simple and fast tool for identifying unknown materials or contaminants.

Analytical Testing News Roundup: Early Breast Cancer Detection, Studying Ancient Humans & Stinky Fruit


February 2017 Analytical Testing News RoundupAnalytical testing techniques are used by companies, scientists and researchers all over the world to make interesting and groundbreaking discoveries.

Here we roundup some of the most interesting and cool bits of news and research featuring analytical testing methods such as Fourier transform infrared spectroscopy (FTIR) analysis and gas chromatography mass spectrometry (GC/MS)in action:

1. GC/MS Shows Promise as Technique for Phthalate Separation

Phthalates are classified as anti-androgen endocrine disruptors, which affect the action of male hormones. As a result, steps have been taken in recent years to restrict their use in items such as toys and childcare products, according to SeparationsNow.

4 Examples of FTIR Analysis at Work in the Manufacturing Industry


FTIR Analysis in ActionFTIR analysis, or Fourier transform infrared spectroscopy, is a useful, accurate and fast materials analysis technique with wide ranging applications—and it’s especially useful for quality control in manufacturing.

If you’re unfamiliar, FTIR is used to identify organic and some inorganic materials through the application of infrared radiation (IR). For manufacturers, this technique can be used to identify unknown materials or contaminants that can or have affected product quality, function or safety. It’s also a technique that’s often used by researchers and scientists in the development of new products.

Below we give you a peek at this versatile analytical testing technique in action.

How Gemologists Use FTIR to Classify Diamonds, Identify ‘Fakes’


Diamond JewelryDiamonds are often touted as some of the most beautiful, elegant and sought-after gemstones on Earth, with many consumers paying top-dollar for the most brilliant stones.

But have you ever wondered what actually makes a diamond a diamond? Or how gemologists are able to identify the real deals?

Fourier transform infrared spectroscopy (FTIR) analysis is a go-to technique in the jewelry world for classifying diamonds, and can also be a helpful tool for spotting synthetics.

What is FTIR?

FTIR analysis is an analytical testing technique used determine a sample’s molecular composition and structure through the application of infrared radiation (IR).

How Analytical Testing Can Uncover Adulterated Foods


analytical-testing-to-uncover-food-adulterationFood adulteration, or food fraud, has emerged as a hot news topic in recent years, but it’s certainly not something new.

According to History.com, humans have been altering food since prehistoric times to increase longevity and improve taste. But overtime adulterating food, which often involves adding fillers or additives, has transformed into something that could be done for economic gain.

“During the Middle Ages [in Europe], imported spices were quite valuable,” History.com explains. “Due to their high prices and limited supply, merchants sometimes combined spices with numerous cheap substitutes such as ground nutshells, pits, seeds, juniper berries, stones or dust.”

Analytical Testing News Roundup: Turning Water into Wine & Craft Beer for Aquatic Conservation


Analytical Testing News Roundup IIAnalytical testing techniques are being used every day by scientists and researchers all over the world to make interesting and groundbreaking discoveries.

Below we roundup some of the most interesting and cool bits of news and research of analytical testing methods in action, many of which involve the making and perfection of adult libations:

1. Brewer & National Aquarium Partner to Create Craft Brew, Support Aquatic Conservation

A Delaware brewing company, Dogfish Head, has teamed up with the National Aquarium in Baltimore to create a brew that pays tribute to sea life, while also aiming to conserve it.

What’s That Stain? Materials Testing Can Give You Answers


What's That Stain?“What’s that stain?”

This is a question that many quality assurance specialists in the manufacturing industry will need to answer at some point in their careers. Stains on products often signal a quality issue that can compromise the safety or function of the product. Fortunately, materials testing can help QA specialists answer that question.

Materials testing is a broad term that refers to the use of analytical testing techniques to identify the chemical composition or characteristics of a sample. Below are some of the techniques that can be used to not only identify surface stains, but also help manufacturers trace the source of the contamination.

How FTIR Analysis Identifies Packaging Defects


Box wrapped in plastic packaging material.For all manufacturers, product packaging is key to protecting a product’s quality, ensuring freshness or eliminating safety hazards. However, packaging materials are becoming more complex as technology advances.  As a result, identifying defects that could sabotage quality is also becoming more complex. For example, many packaging materials are now composed of more thin layers than ever before, which makes it more difficult to detect defects with the human eye.

Fear not. Whether a defect has already been discovered or you’re considering a new packaging material, FTIR analysis can detect visible and microscopic defects that could sabotage quality.

Using Chemical Analysis to Identify the Perfect Packaging


A woman shopping in a grocery storeThey say not to judge a book by its cover, but do you judge products based on their packaging? Consumers tend to be primarily concerned with aesthetics when it comes to a product’s packaging. Marketing teams design packaging to be eye-catching and easy to read. However, there is more to product packaging than appearance. Good packaging should help preserve your product and make it easier to store, ship, and display.

5 Reasons to Outsource Your Quality Control Testing


A male and a female scientist conducting quality control testingWhen a product fails a standard quality assurance check, finding the source of the product or quality defect becomes imperative. An explanation for the quality defect must be found before the manufacturing process can proceed. Unexpected product defects may even stall production, so your job is to troubleshoot the problem as quickly as possible.

When a product fails QA, and you’re unsure of how the problem occurred, what do you do next, and who do you turn to for help?
