Strategies for Achieving the Lowest Possible Detection Limits in ICP-MS
Rene Chemnitzer
A laminar flow box for sampling is combined with a positive voltage on the skimmer cone to reduce detection limits to pg/L concentrations in ICP-MS. These improvements reduce the risk of contamination and increase the efficiency of ion sampling and focusing.

Adsorbate-Induced Morphological Changes of PVD-Deposited Nano-Island Film SERS Substrates
Daniel T. Kwasnieski and Zachary D. Schultz
The morphology and gap spacing of nano-island film SERS substrates are key factors defining the properties of analyte–substrate interactions. These results of the study described here have implications for understanding signal variation in SERS and in designing future SERS assays.
