Content Determination of Amino Acids Using Ion Chromatograph

Amino Acid Analyzer Introduction

There are currently 22 amino acids determined as protein building blocks. Moreover, researchers have discovered roughly 250 non-proteinogenic naturally occurring amino acids. Meteorites and comets have also been shown to have amino acids. The standard 20 amino acids, which are stored in the form of codons in the DNA.

Out of these standard amino acids, the human body or the microorganisms existing in the human digestive system synthesize 12 amino acids and the remaining eight essential amino acids are obtained from food. Conversely, all the amino acids required for plants and microorganisms are synthesized by themselves.

The human health is largely affected by the concentrations of various amino acids. Therefore, it is essential to perform amino acid analysis in different fields. For instance, in the clinical field, the amino acid analysis in physiological fluids like urine or saliva helps diagnose metabolic disorders.

Measuring amino acids in protein hydrolysates helps achieve control over feedstuffs and foods (Figure 1). In the beverage industry, effective process control and media production for cell cultures and fermentation can be achieved through determination of amino acid concentration. Amino acids also play crucial role in producing cheese with the required taste.

Helium leak detector trace every leak.

Helium leak detector from globe-instruments.com, the answer to all your leaks, no matter how big or small
Helium leak detector is too small or too big to escape our leak detectors. It doesn’t matter whether you are looking for water, oil, fuel, refrigerant, gas, steam, air or vacuum leaks. From miniature electronic units right up to large-volume vessels, from media escaping from vacuum systems to gases entering them – the uses for leak detectors are as broad as the range of industrial products. The extensive range of Pfeiffer Vacuum leak detectors provides the answer for all these requirements.

Zp006 Helium leak detector/ gas leak detector

Zp005 Helium leak detector

zp004 Portable helium leak detector

Zp003 helium leak detector

Zp002 Desktop Helium leak detector

Zp001 Helium Mass Spectrometer Leak Detector

Leak detectors for various requirements: portable, compact and stationary units
Our portable leak detectors are used both for mobile leak detection “on site”, such as company premises, as well as for worldwide service jobs in a variety of different locations. Our leak detectors stand out above all due to their high performance combined with low weight.

The compact Helium mass spectrometer are used first and foremost for stationary applications to detect leaks and test for leak tightness. They are also portable thanks to a special leak detector cart. Compact leak detectors are used in widely ranging industries, from applications in heavy industry right up to clean room applications. In this latter case, the dry versions of the leak detectors are being used.

Stationary high-performance leak detectors are used where extremely short cycle times and fast cleanup of Helium background are required. Our leak detectors of the ASM 192 and ASM 1002 series are used in applications ranging from large-scale testing of electronic components for leak tightness up to highly sensitive applications in vacuum and medical technology or research and development.

Leak detection with the test gas Helium: Safe. Quantitative. Repeatable.
Helium leak detectors are the ideal solution for leak detection and leak-tightness testing under vacuum. The test gas Helium is safe and a small, light molecule which is suitable for detecting micro leaks. The detection range of Helium in vacuum tests lies between 10-2 and 10-13 Pa · m3/s. Helium leak detection is extremely accurate, quantitative and repeatable. Fast cycle times are a further advantage.

Manual sniffing or spraying is often the easiest way to detect a leak with Helium. But it is also possible to use automatic leak detection solutions which are independent of the operator and provide a considerably higher detecting speed. The integral leak detection is designed to achieve pre-defined quality and component throughput levels.

The use of test gas leak detection methods has the bonus of delivering extra data compared to traditional leak detection methods such as bubble testing or pressure drop methods. These data can be used to improve production processes and successfully detect every leak.

Amino Acid Analysis from Globe-instruments.com

Amino Acid Analysis

Proteins and peptides are large macromolecules consisting of covalently bonded amino acids. Proteins commonly exist as folded structures, while peptides are shorter linear polymers consisting of only a few amino acids. Amino acid analysis refers to the methodology used to determine the individual amino acids in a protein or peptide that may be part of—for example—a pharmaceutical preparation. Analysis of amino acid content can be used to support protein or peptide structure, evaluate fragmentation strategies, or detect atypical amino acids that may be present. It is necessary to hydrolyze the protein of interest, and the choice of procedures is key to accurate analysis as some sensitive amino acids may be destroyed during the hydrolysis. After hydrolysis, the hydrolyzing reagents are removed (typically by evaporation) and the hydrosylate is reconstituted in water or other compatible solvent. Because most free amino acids are poor chromophores, they cannot be directly detected at low concentrations using ultraviolet (UV), visible (vis), or fluorescence detection. Therefore the hydrolysate must first be derivatized with a chromophoric or fluorometric reagent before detection. This amino acid analyzercan be performed either before chromatography (precolumn derivatization) or after chromatography (postcolumn derivatization). Both pre- and postcolumn derivatization methods are costly for both reagents and labor, add risk of toxic chemical exposure to personnel, and require hazardous waste removal. Electrochemical detection is a good alternative, that doesn't require derivatization after hydrolysis.

Leak Testing Refineries and Process Plants

Reduce Emissions and Save Money

Leaking equipment such as valves, pumps and connectors are the largest source of emissions from refineries and chemical manufacturing facilities.  An average refinery or chemical plant can have 150 to 46,000 valves and 600 to 60, 000 connectors—and can emit over 700 tons of volatile organic compounds each year from valves, connectors, pumps, compressors, and pressure-relief devices.

In refineries and petrochemical plants, saleable products are lost wherever emissions escape from process equipment.   Lost Product=Lost Revenue.  In 1992, the EPA estimated that product lost due to equipment leaks was $1,370 per ton.  Or over $730,000 per year for each facility.   And that’s figured in 1992 dollars!  If you factor in 20 years of price inflation, a good leak detection and repair program can save your facility plenty by reducing lost product.

By implementing a leak detection and repair program with scheduled leak testing of all equipment components at regular intervals, you can run your facility more efficiently, minimize expensive down time and generate cost savings by reducing lost product.   And by reducing emissions and VOCs and VHAPs, you can avoid emission fees, enforcement actions and  regulatory penalties.

With monthly or quarterly monitoring programs Refineries can reduce their emissions from equipment leaks by up to 63%.  And Chemical Plants can reduce VOC emissions by 56%.

Our experienced leak detection technicians can help keep your facility online and running efficiently.
