摘要:
The invention relates to a process for the preparation of a carrier particularly used in serological reactions, and to a carrier produced according to this process. The carrier consists of carbon comminuted to a grain size of 0.30-1.00 micron and suspended in a buffer having a pH-value of 8.2, preferably in a glycine buffer. The quantity of carbon suspended in the buffer should secure, when making the measurement on the spectrophotometer, a transparency of 10-15 percent. The obtained carbon suspension in a buffer having a pH-value of 8.2 is used in analytic reactions, particularly in serological ones.

AGITATING PINS OF A CARBON BLACK PELLET MIXER ARE AFFIXED IN A HELICAL PATTERN ON LONGITUDINALLY DIVIDED SECTIONAL HOLDERS, TWO SECTIONS OF WHICH HOLDERS FORMING AT LEAST ONE HALF OF A COMPLETE HELIX WHEN INSTALLED IN OPPOSITION TO EACH OTHER ONTO AND AROUND THE DRIVE SHAFT OF THE PELLET MIXER. SUCH SECTIONAL HOLDERS ARE QUICKLY REPLACEABLE SO AS TO MINIMIZE MIXER DOWNTIME DUE TO PIN WEAR AND NECESSARY REPLACEMENT.
摘要:
A carbonaceous material of a grain size below 100 Mu is mixed with a reversibly softening binding agent at a temperature above the softening point of the binding agent and in the presence of water or water vapor. There results a doughy mass which is comminuted to the desired grain size. The comminuted material is then subjected to a preliminary low temperature carbonization followed by carbonizing or coking the material and then activating it. The process permits obtaining of small size substantially ballshaped adsorption coke in a highly economical manner.

摘要:
Provided is a granular activated carbon that can be used for applications similar to wood-based steam-activated carbons; and also provided is a method for manufacturing the same. The granular activated carbon is obtained in the following manner. An activated carbon raw material is carbonized, and then pulverized. The pulverized product is then mixed with a calcium component, and the mixture is molded. Subsequently, the molded product is carbonized and activated, followed by washing.
