DPS Quality Control GC Systems - Application Notes

    Every one of these Quality Control Applications can be analyzed using one of the Custom GC configurations of the Series 600 Lab GC. But that is not all, the majority can also analyzed using the Companion 1, or the Companion 2 Portable GC Systems.  Above all, each of these Custom GC Systems gives the same great results. So, whether your analyzing in the Lab, or in the factory, or out in the field, you can rest assured that your Quality Control Analysis results will always be consistent.

Acrylates GC

     Plastics are a multi-billion dollar industry worldwide. One of the most common forms of plastic are produced from acrylates. Acrylates and methacrylates are common monomers, which easily form polymer plastics because their double bonds are very reactive. We generally refer to these groups of polymers as acrylic plastics and note them for their transparency and resistance to breakage. Plexiglas is an example of a clear break resistant acrylic polymer. Because the composition and impurities in the plastics are so critical to their strength and performance, we configure the DPS Acrylates GC Systems with the latest designed high resolution capillary column and the sensitive FID detector to quickly detect these compounds. The Series 600 GC is for analyses in the lab, or use the Portable Companion 1 GC Systems for analyses right where the samples are taken. The fast heating and rapid cooling column oven in every DPS GC vastly increases your sample throughput. The fully integrated Acrylates GC Analyzer Systems are small and lightweight and all Quality Control DPS systems are modular for expandability, upgrades, and easy service.

Alcohols GC

     Alcohols are used to form many important components in many commercial products. We employ the lower alcohols as solvents and antifreezes. Esters of the lower alcohols are employed extensively as solvents for lacquers, paints, varnishes, inks, and adhesives. The plasticizer-range alcohols find their primary use in the form of esters as plasticizers and also as lubricants in high-speed applications such as jet engines. The detergent-range alcohols are used in the form of sulfate esters in detergents and surfactants. Because the analysis of alcohols is so far reaching we configure the DPS Alcohols GC Systems with the latest designed high resolution capillary column and the sensitive FID detector to detect all of these compounds. The Series 600 GC is for analyses in the lab, or use the Portable Companion 1 GC Systems for analyses right where the samples are taken.

Aldehydes GC

     Aldehydes are used for the manufacture of synthetic resins, dyestuffs, flavorings, perfumes, and other chemicals. Low molecular weight aldehydes, such as formaldehyde and acetaldehyde have sharp, unpleasant odors. Whereas, higher molecular weight aldehydes, such as benzaldehyde and furfural have pleasant, often flowery, odors and are found in the essential oils of certain plants. We also use Aldehydes as preservatives and disinfectants. Because of the wide range of components and mixtures we configure the DPS Aldehydes GC Systems specifically with you in mind. We include the latest designed high resolution capillary column and the sensitive FID detector to quickly detect all of these compounds. The Series 600 GC is for analyses in the lab, or use the Portable Companion 1 GC Systems for analyses right where the samples are taken.

Amines GC

     Amines play prominent roles in biochemical systems where they are widely distributed in nature in the form of amino acids, alkaloids, and vitamins. Amines such as epinephrine, thiamin, and Novocaine have pronounced physiological activity. The odor of decaying fish is due to simple amines produced by bacterial action. We use Amines to manufacture many medicinal chemicals, such as sulfa drugs and anesthetics and the important synthetic fiber nylon is also an amine derivative. Because the use of amines is critical to so many industries we configure the DPS Amines GC Systems specifically with your application in mind. We use the latest designed high resolution capillary column and the sensitive FID detector to quickly detect these compounds.

Cresols GC

     The mixture of cresols obtained from coal tar is called cresylic acid. We use the cresols, which are aromatic methylphenols, in the manufacture of disinfectants, household cleaners, deodorizers, certain pesticides, and synthetic resins. They have also been used as antiseptics, although they have largely been displaced by less toxic compounds. We find Cresols in many foods and also use them as a wood preservative. So many industries use these important chemicals that the need for analysis has dramatically increased. To meet this need, we configure the DPS Cresol GC Systems with the latest designed high resolution capillary column and the sensitive FID detector to quickly detect these compounds.

Formaldehyde GC

     Formaldehyde is a simple, highly reactive hydrocarbon that is used as a fixative in the pathology laboratory, as a fumigant, disinfectant, in photographic materials, and in the manufacture of foam insulation, cosmetics, drugs, clothing, and furniture. It is also a major toxic component of photochemical smog. Because of its extreme reactivity, even with itself, it cannot be readily isolated or handled in the pure state. Therefore, it is produced and marketed as an aqueous solution. Due to the health concerns arising from exposure to formaldehyde there has been an increasing need for the analysis of this reactive compound. To meet this need, we configure the DPS Formaldehyde GC Systems with the latest designed high resolution capillary column and the Sensitive HID detector to measure water and other impurities in formaldehyde. The Series 600 GC is for analyses in the lab, or use the Portable Companion 1 GC System for analyses right where the samples are taken.

Glycols GC

     Ethylene glycol is the simplest and most common of the class of glycols. We use it as antifreeze in cooling and heating systems. The next larger compound is propylene glycol, which is similar to ethylene glycol but not toxic, and is used extensively in foods, cosmetics, and oral hygiene products as a solvent, preservative, and moisture-retaining agent. As you go up in size, other important glycols are used as raw materials for plastics and other chemicals, insect repellents, and even tranquilizers. So many industries use Glycols that the need for analysis has dramatically increased. To meet this need, we configure the DPS Glycols GC Systems with the latest designed high resolution capillary column and the sensitive FID detector to quickly detect these compounds.

Silanes GC

     Silanes are structural analogs of saturated hydrocarbons, but are much less stable. All burn or explode when exposed to air and react readily with olefins to form alkylsilanes, which are products we use as water repellents, masonry protection, starting materials for silicones, and in the manufacture of semiconductors. Silanes are also used as coupling agents to adhere glass fibers to a polymer matrix, or a synthetic layer on a titanium implant. With so many uses for silanes, and keeping safety in mind, we configure the DPS Silanes GC Systems with the latest designed high resolution capillary column and the sensitive FID detector to quickly detect these compounds. The Series 600 GC is for analyses in the lab, or use the Portable Companion 1 GC System for analyses right where the samples are taken.

Siloxanes GC

     The word Siloxane is derived from the words Silicon, Oxygen, and Alkane. You can find Siloxanes in products such as cosmetics, deodorants, water repelling windshield coatings, and some soaps. They occur in landfill gas and are being evaluated as alternatives to perchloroethylene for dry cleaning, which is widely considered environmentally undesirable. The polymerized form of siloxanes (polysiloxanes) are similar to silicones and also used as adhesives and moisture barriers. To make sure that all of these compounds can be separated and identified, we configure the DPS Siloxanes GC Systems with the latest designed high resolution capillary column and the sensitive FID detector to quickly detect these compounds. The Series 600 GC is for analyses in the lab, or use the Portable Companion 1 GC System for analyses right where the samples are taken.

Styrene GC

Styrene is a colorless oily liquid which is produced annually by the millions of pounds. The majority of the styrene used is converted into polystyrene, which is a rigid clear thermoplastic polymer that can be molded into objects or made into foam, which we use as a packing material and thermal insulator. Other thermoplastic or even thermosetting resins are prepared from styrene by copolymerization with suitable comonomers. A smaller quantity of styrene goes into the manufacture of synthetic rubbers. Because the composition and impurities in polystyrene are so critical to its performance, we configure the DPS Styrene GC Systems with the latest designed high resolution capillary column and the sensitive FID detector to quickly detect these compounds. The Series 600 GC is for analyses in the lab, or use the Portable Companion 1 GC System for analyses right where the samples are taken.
