o Micron (1 micron= 1 micrometer) § Bacteria and eukaryotic cells in this range (10-100 micrometers) § A filter with 0.2 micron-sized pores will effectively remove bacterial contamination by trapping them in the filter o Nanometer (nm) § Viruses are in this range § 20-100 nm is the typical range of diameters for viruses § The same filter mentioned above will not remove most viruses o Angstrom (A) § Molecules in this range § A nanometer= 10 angstrom • Understand the difference between light microscopes and electron microscopes o Sources of illumination are different:
EDX samples about 1 to 2 micrometers deep into a sample and the emission volume is about 1 micrometer wide, so the resolution is much lower in EDX mode than in SED mode.

2 Sensors and Data Piezoelectric Actuator Lab • • • • • Used a motor with a fine travel range of 25 micrometers Inputted 5 V signal at 5hz Measured movement with Linear Variable Displacement Transducer (LVDT) and National Instruments LabView Used filters to account for noise Looked for 5hz signal in LabView
• Your external measurement needs are covered by classic instruments such as TESA micrometers.
Air cleaners usually meet the HEPA (High Efficiency Particulate Air) filter standard, which can eliminate any foreign material less than 0.03 percent of particles 0.3 micrometers in size.
