Current Products Turbidity Meters (~$800s -

$1000s) Advantages

Cost Less than Spectrometers

Small and Portable Disadvantages

Cannot do color detection on samples

Usually implement detection by use of vials (not real-time analysis)

Current Products Mass Spectrometers

(~$100,000s) Advantages

High resolution detection of a sample’s color content

Very Accurate and Stable System

Disadvantages Not a real-time analysis Bulky and Not portable Very High Cost

Current Products Mini Spectrometers (~$2000s)

Advantages Cost Effective Solution to Mass

Spectrometers Compact Size Can be implemented to do real-

time analysis Disadvantages

Cost More than Turbidity Meters Lacks some resolution and

accuracy to mass spectrometers
