Product Chemistry Testing

All these products may contain toxic or restricted chemicals: adhesives, beverages, drugs, electronics, food, gas, furniture, metals, minerals, oil, paints, plastics, rubber, soil, solvents, textile, and more.

Therefore, new products or resource deposits will often require chemistry testing since producers try to comply with various regulations or standards. For example, hazardous and restricted substances need careful monitoring, and unwanted compounds found in a mineral assay can spoil an entire dig site. 

Then, depending on your industry, you may have concerns about one or more molecular compounds inherent to your processes. Confirming the presence or levels of a target compound in this way requires sophisticated molecular analysis techniques.

Molecular Analysis with Enviropass

With Enviropass, you get access to cutting-edge technology for your chemistry testing. 

  • The lab receives, handles, and prepares your sample for treatment in-house. This approach eliminates delays from data-sharing and additional transport.
  • Solid-phase molecular testing saves costs and time by reducing or avoiding pre-analysis workup.
  • Minimally destructive techniques ensure peace of mind when dealing with sensitive materials or prototypes.

What is Molecular Analysis?

First, terms like chemistry testingchemical analysisanalytical testing, or chemistry analysis can refer to verifying substances in materials at the molecular level.

Chemistry testing of products often falls into one of two categories. 

First, elemental analysis determines the presence of elements in a sample. This information applies to many industries: for example, trace metal analysis is a common practice in resource extraction and intermediates manufacturing. Elemental analysis is also the leading tool for detecting hazardous substances like heavy metals.

On the other hand, detecting molecules is often a more involved procedure. Molecular analysis can be more complicated and expensive than elemental analysis. Therefore, techniques for studying molecular composition are often less available to suppliers or producers that cannot implement this analysis in-house.

What can Molecular Analysis do?

Some elements are undesirable due only to their presence. Such is often the case with heavy metals like lead or cadmium. The story is more complicated, however, with smaller and simpler elements like carbon. Indeed, we can use the same set of atoms to create many unique molecules simply by connecting them differently. Molecular analysis techniques must account for this added complexity; therefore, they are often more sophisticated.

Chemistry testing of a product at the molecular level can help determine the presence of many substances of interest, including:

  • phthalates and parabens
  • long-chain PFAS 
  • other organohalides
  • formaldehyde and glycols
  • phenols and benzoic acids
  • other hazardous or restricted substances
  • small proteins

Chemistry Testing: Molecular Analysis via Mass Spectrometry

There are many ways to analyze a sample at the molecular level, and the implementation depends on your needs. A popular method is a mass spectrometry, which separates constituent molecules according to their relative masses. Compounds will display signature characteristics in the resulting spectrum, allowing the identification of target molecules. 

Mass spectrometry is a well-tested, well-understood technique that has evolved significantly over the years. The analysis begins by ionizing the molecules on a small sample. These tiny fragments are collected and funneled into a beam of ionized particles. This beam passes through a filter that exerts a force on each particle depending on its mass. 

Generally, heavier molecules are not as susceptible to the field of force and will fly farther than light particles. Eventually, each particle falls out of the ionized beam and crashes into a charge detector plate. This collision determines the particle’s weight based on where it strikes the detector.

Modern Developments in Mass Spectrometry

Traditional methods for mass spectrometry represent early attempts at performing this analysis. Researchers have refined these techniques over the years, of course. However, newer techniques can improve accuracy, reduce costs, and dramatically increase sample throughput.

Laser-Assisted Sample Extraction

One example is laser-assisted sample extraction, which replaces early thermal and electrospray methods. Laser technology can produce lower detection limits than traditional ion-forming methods with comparable (or improved) accuracy.

Solid-Phase Mass Spectrometry

Secondly, solid-phase mass spectrometry has become very popular due to the potential for rapid turnaround times. Sample preparation time is negligible compared to gas- or liquid-phase analysis since analysts do not need to dissolve or vaporize the sample. This methodology works well alongside laser extraction since it reduces special handling procedures further. With good conditions, sampling times of only a few minutes are possible.
