This is an informational tour in which students gain a basic understanding of geologic time, the evidence for events in Earth’s history, relative and absolute dating techniques, and the significance of the Geologic Time Scale.
Beta Analytic uses Accelerator Mass Spectrometry (AMS) technology, which gives the most advanced precision and accuracy for carbon-14 measurements.
Though you will be paying more for this optimum water filtration, it does offer peace of mind and you'll find it well worth the price.

Beta Analytic’s radiocarbon dating fees are inclusive of δ13C measurements by Isotope Ratio Mass Spectrometry (IRMS) and calendar calibration when applicable, δ18O for carbonates, and δD (deuterium) and δ18O for water.
The lab also offers C: N, %C and %N measurements on collagen extracted from non-cremated bones in addition to δ15N and δ13C at no additional cost for samples sent for radiocarbon dating.Such layered filters are considered more effective since they have the ability to filter smaller particles from the water.It really depends on what the filter is designed to achieve in filtering out waterborne particles.This is essential to maintain its filtration efficiency.Coal is the most common element used to activate carbon filters, but manufacturers will often enhance the carbon by using other elements or layers and blends of materials in their designs, including spun fibers.The size of particles absorbed depends on the size of the pores or micron rating.
