RESEARCH METHODS

• incubation - process of maintaining favorable conditions for growth and development i.e., microbiological culture
• what are the common chemical techniques?

  1. spectrophotometry
  2. extraction
  3. titration
• spectrophotometry - this method by which you measure the amount of absorbtion and transmittance of light
• spectrophotometer - is a device that measures the number of photons.
• what is this?

  digital spectrophotometer

  
• spectrometer - is a device that disperses and measure light
• what is this device called?

  spectrometer

  
• photometer - consists of a photoelectric detector that measures the intensity of light
• what is this device called?

  photometer

  
• extraction - this is the conversion of compounds from a solid or liquid state to another phase or state
• titration - this is the process of determining the concentration of a solution.]
• who said that defined titration as a common laboratory method of quantitative chemical analysis that used to determine the unknown concentration of an identified analyte?

  medwick & kirschner 2010
• there are two types of titration, what are the two?

  acid - base titration and redox titration
• acid base titration - depends on the nuetralization between an acid and a base when mixed in solution
• aseptic techniques - it is done to lessen the chance ofbacteria contamination.
