Abstract
Balances with adequate sensitivity to measure the small weight changes associated with adsorption can be divided into two categories — electronic beam microbalances and spring balances. Electronic beam balances usually use an electric current to restore the beam to the horizontal position as the weight changes. Their sensitivities are in the order of 1 µg with loadings of approximately 1 g. Commercial electronic microbalances are available in vacuum containers with appropriate fittings for vacuum pumps and gauges.
