Stable Isotope Analysis

Carbon-14 & Stable Isotope Analyses of Marine and Freshwater Carbonates

Carbonates are widely used in geology, paleoclimatology and paleontology as the oxygen and carbon therein are foundational for radiocarbon dating and stable isotope analyses.

Why are Pteropods Excellent Recorders of Climate Change

Pteropods are sea slugs of <1cm in size, which originated approximately 133 million years ago in the Early Cretaceous. They are commonly analyzed in modern climate as well as paleoclimate studies due to their abundance within the water column as well as their vulnerability to changing environmental conditions.

The Suess Effect: Why is it important?

Since the start of the industrial revolution, carbon dioxide (CO2) has been accumulating in the atmosphere as a result of human activities (e.g. combustion of fossil fuels and land use change) – with an increase of over 100ppm CO2 in the past 60 years alone.

Radiocarbon Dating and Isotopic Analysis of Insects (Chitin)

The remains of insects are dated using the exoskeleton made of chitin, which is a fibrous substance made up of polysaccharides. Given the very small size and weight of the exoskeletons, they have historically been very difficult to date.

Beta Analytic Offers Free Stable Isotope Analysis for Water

Beta Analytic is expanding its services for groundwater and, for a limited time, is including free additional measurements when clients submit samples for radiocarbon dating. The laboratory is including isotope ratios for deuterium (dD) and oxygen (d18O) at no additional cost for all water samples submitted for accelerator mass spectrometry (AMS) dating until August 2016.

Beta Analytic Offers Free d15N and d18O Testing to Clients

In an effort to further support ​its ​clients’ research, Beta Analytic will provide free d15N measurements on non-cremated bones and d18O on carbonates submitted for radiocarbon dating. The ISO 17025-accredited lab has recently removed its micro-sample analysis fees and cancellation fees for samples that are too small for standard AMS dating.
