The program seeks to find mechanisms and their rates for all fragmentation types (EI, Tandem positive and negative mode) and correlates mass spectral peaks to a probable origin structure. It contains an isotope calculator and other features and on-line help. This program is a companion to the NIST Spectra Search Program, v.3.0.
The SpectrAlert series included horn strobes, strobes, remote horns, chimes, chime strobes, speakers, and speaker strobes. A main feature of these alarms was the ability to sync them using a System Sensor MDL sync module or the System Sensor sync protocol on a supported fire alarm control panel. Three years after the initial release of the ...
In the late 1990s, Underwriters Laboratories changed the definition of a single station CO detector with a sound device to carbon monoxide (CO) alarm. This applies to all CO safety alarms that meet UL 2034 standard; [ 1 ] however for passive indicators and system devices that meet UL 2075, UL refers to these as carbon monoxide detectors .
NIST had an operating budget for fiscal year 2007 (October 1, 2006 – September 30, 2007) of about $843.3 million. NIST's 2009 budget was $992 million, and it also received $610 million as part of the American Recovery and Reinvestment Act. [18] NIST employs about 2,900 scientists, engineers, technicians, and support and administrative personnel.
NIST NCSTAR 1-4: Active Fire Protection Systems. NIST NCSTAR 1-4A: Post-Construction Fires prior to September 11, 2001; NIST NCSTAR 1-4B: Fire Suppression Systems; NIST NCSTAR 1-4C: Fire Alarm Systems; NIST NCSTAR 1-4D: Smoke Management Systems; NIST NCSTAR 1-5: Reconstruction of the Fires in the World Trade Center Towers
This is a list of Superfund sites in Massachusetts designated under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) environmental law. . The CERCLA federal law of 1980 authorized the United States Environmental Protection Agency (EPA) to create a list of polluted locations requiring a long-term response to clean up hazardous material contamination
Notifier or Notifier by Honeywell is a manufacturer of engineered fire alarm systems with over 500 distributors worldwide, and regional support operations on every continent. [1] Notifier is headquartered in Northford, Connecticut , United States, and is a division of the Honeywell Life Safety Group.
Find mass differences at 28 Da since b-ions can form a-ions by loss of CO. Look for b 2-ions at low-mass end of the spectrum, which helps to identify y n-2-ions too. Mass of b 2-ions are listed in Table 2, as well as single amino acids that have equal mass to b 2-ions. [15] The mass of b 2-ion = mass of two amino acid residues + 1. Table 2 ...
