 Auto sampler with specified features  CO2 flow system  In line safety bottle  Flushing system  Sample mixing/stirring  Heat control  Interface with mass spectrometer

 Radical change in design, due to refined scope from outside advisor.  Needed to add heat control and stirring mechanism  After further research into part cost, previous designs greatly exceeded budget  New design is simplified, requires slightly more human interaction, but meets the needs of project scope much better

 2-Way Solenoid Valve  Closed when off  PTFE (Teflon)  Designed for gases

 Re-sealable septa bottle tops (Teflon)  Needle puncture  Inlet/outlet design  Works in conjunction with valving system

 10 zones  Heat plate, with temperature control kept at 37 degrees Celsius  Up to 1100 RPM, will be kept at 200 RPM

 Software interface  Assembly, due to high tolerance, and sensitive parts  Straight line motion of the enclosure top  Test needle gauge by puncturing septa top and determining if sticky pad will hold bottles  Staying in budget
