  • Located in Penthouse

order of operation

  1. LCMS solution software
  2. Turn on gas 120 psi Nitrogen
  3. Open Window
  4. LCMS solution Analysis 1>Data>Instrument parameters >Scan mode 50-600>Sample Settings> 5 min run time because there was not a column
  5. Must always make sure controller has a stop at end of program
  6. Created a Tami Tinsley folder in CHEM 605, save all data there
  7. Tested SHMP for Ash for Test 1 > 1ml per min, isocratic flow
  8. 093015Tunning program
  9. 5µL column use 10µL of sample to inject > must use blunt tip for injection
  10. Test 2 reduced flow rate to 0.250 for both pump A and B
