class="label">•: Comparison of low power Mo and W-TXRF systems for multielemental analysis of wines
class="label">•: Wine samples can be analyzed by depositing 10 μL of the standardized sample using Ga.
class="label">•: Light element recoveries can be improved after wine dilution.
class="label">•: LODs for light-medium Z elements are one order of magnitude lower for Mo-TXRF system.
class="label">•: Better sensitivity for high Z elements (i.e., Cd) is obtained using W-TXRF system.
