A multichannel in-vitro metabolism real-time monitoring apparatus includes a radiation probing apparatus and a constant flow culture apparatus. The constant flow culture apparatus includes a liquid supply bottle, a waste liquid bottle, a multichannel infusion apparatus, and a multichannel liquid separation apparatus. The radiation probing apparatus has two groups of probing modules with flat structures, which are separately disposed on two sides of multichannel biochemical culture apparatuses and are used for recording radiation activities in the multichannel biochemical culture apparatuses in real time.

A method for real-time processing of a pulse pile-up event comprises the following steps of: generating a fitted baseline value lookup table and a fitted energy value lookup table for a pulse falling edge, using a multi-voltage threshold sampling method to identify piled-up pulses and trigger a procedure of processing pulse signals; and using pulse priori information and acquired pulse information to acquire information of an incorrectly sampled portion due to a pulse pile-up by looking up in the tables, so as to recover information of the pile-up pulses in real time. First, in the disclosure the multi-voltage threshold sampling method is proposed to identify pile-up pulses at a high count rate and trigger a procedure of processing pulse signals. Next, pulse priori information and acquired pulse information are used to acquire information of an incorrectly sampled portion due to a pulse pile-up by looking up in the tables, to recover information of the piled-up pulses in real time. The method according to the disclosure is simple, highly efficient, can be realized easily in a real-time data acquisition system of a detector level, and is still capable of achieving a preferable effect of recovering formation of piled-up pulses at a low sampling rate.
