Are you ready?

How will you detect it, and are your methods fast enough?

MALDI-TOF Mass Spectrometry can identify sub-species in under 2 minutes

Red lines indicating a spectrum match

Algae is toxic and it Kills

LCMSMS Analysis of Microcystins

Polar pesticides and herbicides are difficult by GC

Analyze pesticides and herbicides by LCMSMS, with very little sample prep

Analyze pesticides and herbicides by LCMSMS, with very little sample prep

We can analyze hundreds more pesticides with high selectivity and sensitivity by GCMSMS

Methods can retain full scan capability and add MRM for greater selectivity and sensitivity

Qualification Quantification

Analysis of solid waste for metals requires acid digestion and instrumental analysis,

Or,

And create new methods that use XRF

X-ray tube

Primary X-rays

Horizontal axis: Energy (keV) = Type of element

Vertical axis: X-ray intensity (cps/uA) = Concentration (ppm)

Should we continue with the Kjeldahl Method for TKN?

Or use HTCO methods and obtain near equal results with TKN

Technology is advancing faster than the methods

It’s time for some new stuff

• MALDI TOF – New, faster way to confirm bacteria

• LCMSMS – Emerging Contaminants not visible before

• GCMSMS – more sensitive, higher throughput

• XRF – no digestions, higher throughput

• NOx – safer, non toxic reagents

• TN – safer and higher throughput than TKN
