title: [Time-base sweep unit for polarograph PA-2].
abstract: A time-base sweep unit is proposed for a PA-2 polarograph (Czechia). The apparatus as a further development of a series of voltamperometric analyzers of the known mark "LP" has a number of additional modes of polarographic analysis expanding the possibilities of recording the volt-ampere characteristics of the analyzed objects. However, the apparatus cannot solve the problems pertaining to a temporal evaluation of biochemical processes, for estimation of oxygen consumption in particular as it has no a time-base sweep function (I/t), which records only volt-ampere characteristics. In this connection, a time-base sweep unit was elaborated and included into the apparatus complex that provides time-base sweep along the coordinate. The modularity of the proposed elaboration permits its use in other types of polarographs that have no time-base sweep function.
