Retention on TLC plates is measured in Rf (retention factor), whereas in column chromatography, it is usually expressed in CV (column volumes): R f = (distance traveled by desired compound) / (distance traveled by solvent) CV = 1 / R f
America Real Estate Investment Group LLC offers a wide range of products & services from investment properties to property management on an international global scale.
In all of these areas, the American funds excel. In short, I believe American is the best large fund family that specializes in actively managed funds. My favorite American funds are Fundamental Investors (ANCFX), New World (NEWFX) and New Perspective (ANWPX).I donât care for Smallcap World (SMCWX), and Iâm not a fan of Americanâs bond funds.ut if you look at the pattern of money flowing into and out of the funds, youâll understand why they decided to âgo public.â The American funds have lost more than $200 billion in assets over the past few years. The firm is still huge, with $1 trillion under management, but itâs hurting.
