A Solid Phase Peptide Synthesis (SPPS) device and method of using the same for manufacturing peptides is taught herein. The system comprises at least two reactors, each reactor including a quantity of SPPS resin. The reactors are positioned in series. A de-protecting agent is added to the first reactor and then transferred to the second and third reactors, in series, thereby operating to de-protect the protected N-group. Wash solvent is added to the first reactor and then transferred to the second and this operation repeated several times. Likewise, an amino acid activated ester solution is added, in series, to the first, second and third reactors, thereby operating to couple the amino acid to the de-protected N-group. Wash solvent is added to the first reactor and then transferred to the second and this operation repeated several times prior to the next cycle. The use of the reactors in series reduces the overall solvent required. Online LCMS is also used to monitor progress and identity of reactions happening within the solid phase resin particles.

A substrate for use in mass spectrometric analyzes having an array of target locations.

Disclosed herein are compositions, methods and systems for the processing of chemical reactions, such as the synthesis of polymers.

A device capable of synthesizing a plurality of selected peptides by automatically mixing various amino acids, solvents, and activators and adding these to resins contained in a plurality of individual reaction vessels. A plurality of amino acids are contained in vessels within a carousel which is rotated into position where a syringe is inserted into a selected vessel to transport the amino acid within to a pre-reaction vessel for mixing with other selected amino acids which were previously drawn from the carousel. The mixture of amino acids is then transported to a reaction vessel containing the resin balls for growth of the selected peptide. The device includes a computer, controllable valves, at least one pump, pressurized gas such as nitrogen for transporting fluids, various vessels containing amino acids, solvents, activators, resins, and tubing connecting these elements. The computer is programmable to sample, mix selected components, and apply the mixture to resins for growing peptides.

Methodology and apparatus for on-line UV monitoring of automated synthesis reactions. An apparatus includes a module with a fluidic cell the operational parameters of which remain substantially unchangeable not only during the process of monitoring but also in time between sequential processes. The module includes a separable housing structure containing a source of UV-light and an optical detector integrated with substantially temperature-insensitive fluidic cell. A portion of the cell is defined by a slot formed in a cell-chassis and complemented with inlet and outlet dimensioned to ensure that no air-bubble(s) and/or stagnating fluid is present in the cell during time when liquid reactants to-be-measured are delivered through the inlet into the cell. The method is configured to determine progression and completion of the reaction(s) and modification of reactions' times and repetitions of reaction(s) s in real time.

Provided is a full-automatic radiopharmaceutical production apparatus including a synthesis device. The synthesis device includes a synthesis cassette and a main synthesis unit. The synthesis cassette includes a synthesis cassette body. The synthesis cassette body includes a first common pipe extending in a left-right direction. The first common pipe is located between three-way valves that are adjacent in the left-right direction. The main synthesis unit includes a main synthesis unit frame. The first common pipe is detachably fixed at a front housing of the main synthesis unit frame by a first fixing assembly.

A reactor system is disclosed. The reactor system includes a vessel configured to contain a solid support, the vessel including: a vessel wall defining a reaction chamber, the reaction chamber having a first end and a second end opposite the first end; a piston operatively arranged at the first end and configured to translate within the reaction chamber; a force measuring device coupled to the piston and configured to measure a load on the piston; a piston driver coupled to the piston; and a processor operably coupled to the force measuring device and the piston driver, the processor configured to: measure a load on the piston using the force measuring device, and adjust a position of the piston using the piston driver based on measuring the load on the piston.
