WhatsApp: +86 18221755073Where 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).
WhatsApp: +86 18221755073A high-resolution sampling technique for stable-isotope measurements in otoliths is now available, but little is known about the precision and accuracy of the results when using this technique. Otolith samples of pen-reared cod (Gadus morhua L.) with well-defined temperature history were obtained using this high-resolution sampling technique. Samples from different …

WhatsApp: +86 18221755073Key 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.
