Water analysis

Collect sample (1-L bottle)

Ship to lab (at 4°C)

Wait…

Three-week process

$MM equipment and $$ scientists

Raman spectroscopy

1920s 1990s 2000s

Observe vibrational,

rotational, and other

low-frequency modes

in a system

Rayleigh Raman

1 in 10 million photons Spectroscopy ≠ spectrometry

Low concentration analysis?

Use Surface-Enhanced Raman Spectroscopy

ppm-, ppb-, and even ppt-level detection

Internal

standard

(sulfate-18O)

Sulfate

SINGLE-USE CONSUMABLE BUSINESS MODEL

With a $20K handle!?

Current spectrometers

Market size for lead (Pb) analysis

Integrated

photonics

Market size for lead (Pb) analysis
