A-State Closing Early Thursday, Jan. 9, Closed Friday

Arkansas State University is closing all academic and business offices at 4 p.m. on Thursday, Jan. 9, and remaining closed on Friday, Jan 10, in response to the incoming inclement weather.

However, while regular business offices are not open, the campus continues to operate. Essential personnel who maintain on-campus activities, including University Housing, Dining Services and Facilities Management, will report to work. Employees who are uncertain about their status as “essential personnel” are encouraged to check with their supervisor.

Full-time employees who track working hours can submit their time as “Authorized Leave.”

Revised Facility Hours:

  • Dining Services will operate under brunch hours at Acansa Dining Hall from 10:30 a.m. until 2 p.m.  Dinner service will begin at 4:30 p.m. and end at 7 p.m.  Howl's Grill and Starbucks will be open from 8 a.m. until 2 p.m.  
  • The Dean B. Ellis Library will be closed, but is scheduled to reopen on Sunday, Jan. 12, from 2 p.m. until 9 p.m.
  • The Reng Student Union will open for on-campus student usage at 8 a.m., closing at 8 p.m.

MASS SPECTROSCOPY

Mass SpectrometerThe small molecule analyses are supported by their separation through a Thermo Scientific, UltiMate™ 3000 (pump, autosampler, column oven, UV-visible detector) HPLC system followed by their fragmentation through a Thermo Electron Corporation, LTQ-XL™ linear ion trap mass spectrometer (MS).

Differently than single quadrupole and triple quadrupole mass spectrometers (Selected Ion Monitoring [SIM] or Selected Reaction Monitoring [SRM], respectively), linear ion trap systems enable Consecutive Reaction Monitoring [CRM], which are successive fragmentations, resulting in precise species identification in every mass spectroscopy (MSn) step and facilitating molecule structural characterization. The LTQ-XL provides high-sensitivity mass data analyzes in the range of m/z 50-400.

The instruments are supplied with helium and CO2 gasses and their operability is handled by the Thermo Scientific Chromeleon™ and the XCalibur™ suites.
