We carried out a high-precision stellar parameters and abundance determination by applying non-solar-scaled opacities and model atmospheres. Our sample is composed by 20 stars including main-sequence and evolved objects. Opacities for an arbitrary composition and vmicro were calculated through the Opacity Sampling method. We obtained a small difference in stellar parameters derived with non-solar-scaled opacities compared to classical solar-scaled models.
