A technician with a drug
manufacturing company is responsible for the installation and operation of
membrane-based separation equipment that performs the last step in the
production of a drug the company makes. That purification step uses a membrane
to separate the drug from its reaction by-products. The tech understands that
the separation is diffusion-driven which means that drug moves from a solution
with contaminates on one side of the membrane into a liquid with no
contaminates on the other side of the member. Thus, after the tech installs the
equipment and it begins to operate she knows there will be no drug in the pure
liquid at the instant the equipment is turned on.
The tech also knows
that there is a sensor in the pure liquid that only monitors the increase in the
number of drug molecules as a function of time. Since (once it is installed)
this equipment is expected to operate 24 hours a day, the sensor data collected
is used to monitor the equipment’s performance and indicate when there might be
maintenance issues as the equipment keeps running. The tech observed the data shown (in the
graph below) immediately after the equipment was turned on for the first time.
Did Tech allow the equipment to
keep running? Yes or No. Post your answers below the blog post, or on www.fl-ate.org.
