tinpacwe would like to show you a description here but the site wont allow us.learn morehow are column efficiency, peak asymmetry factor, tailinghow are column efficiency, peak asymmetry factor, tailing factor and resolution calculated? > back to hplc faq column efficiency calculation. column efficiency, indicated as the number of theoretical plates per column, is calculated as n = 5.54 (t r / w 0.5) 2 where t r is the retention time of the analyte of interest and w 0.5 the width of the peak at half height.
sand casting process, defects, designthe packing of the sand is also automated in a process known as flaskless ming. despite the name of the process, a flask is still used. in conventional sand casting, a new flask is used for each m. however, flaskless ming uses a single master flask in an automated process of creating sand ms.
