Micromill and in situ laser ablation sampling techniques for high

Key advantages of our LA technique are, for example, high spatial resolution analyses and the possibility of rapid determination of numerous coeval sub-samples. The results on micromill samples are more precise but this sample preparation technique is time consuming and larger sample sizes than used for LA are needed for individual measurements.

Micromill and in situ laser ablation sampling techniques for high

The same section of SPA 59 was analysed at even higher spatial resolution using the micromill technique. Fig. 5 shows the results compared to TIMS (Holzkämper et al., 2005) and MC-ICPMS results on wire saw samples. Within the analytical uncertainties the results are in good agreement. Below the white layer we obtained ages between 194.4 and ...

Precision and accuracy of stable isotope signals in otoliths of pen

Otolith samples of pen-reared cod with well-defined temperature history were obtained using a high-resolution sampling technique, and it was found that the otolith δ13C values had a cyclic pattern, roughly in phase with the δ18O values. A high-resolution sampling technique for stable-isotope measurements in otoliths is now available, but little is known about the precision and …

Resolution

Where r is resolution (the smallest resolvable distance between two objects), NA is a general term for the microscope numerical aperture, λ is the imaging wavelength, NA(obj) equals the objective numerical aperture, and NA(cond) is the condenser numerical aperture. Notice that equation (1) and (2) differ by the multiplication factor, which is 0.5 for equation (1) and 0.61 for equation (2).

High resolution micromill sampling for analysis of fish

Otoliths are calcified structures in the head of fish that record environmental information about fish's life history. Gathering the elemental information from the core of an otolith corresponding to the juvenile period of fish's life is critical to discriminate the adult fish to their natal habitats reliably. A high resolution micromill has been used to isolate the otolith core from a ...
