PTR-MS Technology Introduction: Proton Transfer Reaction Mass Spectrometer (PTRMS)
PTR-MS technology has addressed several of the limitations of mass spectrometers, which can only operate within the confines of a laboratory. PTRMS is a "soft" ionization mass spectrometer. PTR-MS is adept at identification and measurement of volatile organic compounds (VOC's) in the air. PTR-MS can provide information for air quality source apportionment studies to gain insight of the sources of air toxics. Other studies have used PTR-MS for the detection of emissions from sources like biomass burning, cooking activities, diesel exhaust, materials emissions, plus investigation of indoor air quality and vapor intrusion studies.

Stress Corrosion Cracking - Determination, Identification, and Analysis of Stress Corrosion Cracking
Просмотров 1,2 тыс.2 года назад
Stress corrosion cracking (SCC) is an environmentally driven failure mechanism that can be found in metal alloys of all types including pure metals, though pure copper is thought to be immune to SCC. Learn more about stress corrosion cracking determination, identification of stress corrosion cracking, and analysis. This is a Materials Insights article by RJ Lee Group, Inc.
Respirable Crystalline Silica - When are Low Detection Limits Needed?
Просмотров 202 года назад
OSHA requires a 5µg/filter standard detection limit for respirable crystalline silica, but when might your business need a lower detection limit? Equipment and technical enhancements ensures our laboratory can now report detection limits down to 2.5 µg/filter. Industrial hygiene and EHS professionals may be interested in lower detection limits for respirable crystalline silica.
Damage Claims from Nuisance Dust - for Environmental Attorneys
Просмотров 552 года назад
Many industrial operations like construction or building collapse can cause nuisance dust allegations, and under some circumstances failure to limit dust emissions can lead to significant fines from local environmental regulators and lawsuits filed by neighboring property owners. This quick presentation is entitled Nuisance Dust Damage Claims: Evaluating Allegations of Property Damage Due to Su...
Total Crystalline Silica Analysis
Просмотров 532 года назад
Protect workers from respirable or total/bulk crystalline silica. Look for determination of total and respirable crystalline silica in both air and bulk materials. Your site may need accurate quantification for bulk and total crystalline silica using a modified version of the NIOSH 7500 method. This is done to analyze for potential for release of crystalline silica during the mining or manufact...
Crystalline Silica Analysis with XRD
Просмотров 2592 года назад
X-ray diffraction (XRD) is a powerful, nondestructive technique for characterizing crystalline materials. RJ Lee Group just added the new XRD Panalytical Empyrean with BBHD optics and 1Der detector. This state-of-the-art technology increases throughput, eliminates redundancy, and gives better resolution and sensitivity. XRD can provide insight into materials called interferences which may preve...
Steel Inclusion Analysis
Просмотров 6602 года назад
Inclusions are particles of insoluble impurities formed during steelmaking and casting operations that are entrapped during solidification of metal. These inclusions can affect the quality of steel in many ways - such as strength, corrosion resistance, and machinability - and can also impact the steelmaking process itself through phenomena such as nozzle clogging and erosion. With an ever-incre...

Unknown Substance Idenfication
Просмотров 4223 года назад
Unknown substances are contaminants in process quality control. Unknown substances such as impurities or adulterants can not only affect your product, but may pose potential health risks. Analysis of unknown substances found during the quality control process must be identified and their source located so corrective action can be determined.

Air Sample Analysis - Respirable Crystalline Silica
Просмотров 843 года назад
In April 2016, the Occupational Safety and Health Association (OSHA) passed new regulations for crystalline silica exposure limits in the workplace. The regulations include a reduction in the permissible exposure limit (PEL) to 50 micrograms per cubic meter (µg/m3 ) and an action level of 25 µg/m3. Employers in the construction industry were required to comply with the new standards by June 23,...

good work
Lets just say there was a CD, and a underground mini nuke was detonated. Wouldn't that account for the melted and vaporized metals? Molten metal was seen months later deeper underground. Other studies were made and came up with those results of I Beams being vaporized. Then there were the horizontal ejections of the towers. The USGS report showed high levels of barium, strontium, sulphur.....There were other rare metals that shouldn't of been there. Theres the blast waves. Then theres the cancers. If you compare the cancers of responders to the cancers of the crew of the USS Reagan crew who went to Fukushima, they are similar in time and type of. Also over 1140 people were vaporized. To have that many people totally disappear would not happen in an office fire. It takes bout an hour to cremate a body.
