Direct analysis by Ion Chromatography is attractive for Halogen and Sulfur.
But various material has to be prepared adequately to the aqueous solution. To do this, bomb-absorbing method is often used. Even this method there are issue that abnormal combustion could occurred for polymer and organic solvent sample, and also way of absorbing requires know-how to obtain sufficient result.
Automatic sample combustion AQF -100 is able combustion - Ion chromatography measurement by automatically. This instrument enable low level analysis of Fluorine/Chlorine/Bromine/Iodine/Sulfur of organic, inorganic sample in faster and easier.
By combine of sample combustion and IC, halogen/sulfur analysis of organic and inorganic sample is able more easily than before. It is applicable for various industries like polymer, additives, composite for electronics, coal, cement, etc.

IC and RFIC Columns
Hydroxide-Selective Anion Columns
Hydroxide-selective, anion-exchange columns are optimized for use with a hydroxide eluent. Choose a hydroxide eluent column for use with an eluent generator for gradient work or trace analysis. Hydroxide eluents for isocratic or gradient elution are very convenient with Reagent-FreeTM Ion Chromatography (RFICTM) technology using electrolytic generation of the eluent. RFIC technology simplifies methods development for hydroxide-gradient systems since the electrolytic eluent generator provides gradient methods that are simpler to use than manually prepared isocratic eluents. Modern continuous-eluent-suppression systems are designed to suppress hydroxide eluents, even at very high eluting strengths.
Carbonate-Based Anion Columns
Each of these anion-exchange columns are optimized for use with a carbonate/bicarbonate eluent. Carbonate eluent columns are useful for well-characterized isocratic separations, including regulated methods for drinking and wastewater.
Specialty Anion Columns
Specialty columns are anion-exchange columns that can be used with nonsuppressible eluents such as nitric acid in combination with a variety of detection modes, including amperometric and UV-VIS detection.
Cation Columns
Cation-exchange columns are designed for high-resolution separations of inorganic cations, ammonium, amines, and transition metals. These columns provide an excellent approach to separations of alkylamines, alkanolamines, and quaternary ammonium ions.
Transition Metal Columns
Transition metal columns are designed for determination of transition and lanthanide metals in diverse sample matrices.
Ion Exclusion Columns
In ion-exclusion separations, Donnan exclusion causes strong acids to elute in the void volume of the column. Weak acids that are protonated in the acidic eluent are not subject to Donnan exclusion and penetrate into the pores of the packing. Separation is accomplished by differences in pKa, size, and hydrophobicity.
Trap Columns
Trap columns are short columns installed in the system to prevent unwanted analytes from interfering with the separation of your analytes of interest. IonPac trap columns contain high-capacity, low-efficiency, ion-exchange resin. The columns strip trace contaminants from the eluent and prevent them from reaching the guard and analytical columns. The trap is installed in the eluent line prior to the injection valve to prevent spurious peaks during gradient chromatography. These trap columns are specialized columns that remove unwanted analytes from the sample, and are installed before the analytical column.
Concentrator Columns
IonPac concentrator columns are designed primarily for high purity water analysis. The concentrator column strips ions from a measured volume of an aqueous sample matrix, concentrating the analyte species and lowering detection limits.

TMC428
Description
3-axis economic miniature microstepping stepper motion controller
The TMC428 is a miniaturized low cost, but high performance stepper motor controller for up to three motors. It integrates all real time critical tasks in reliable, dedicated hardware: An integrated motion ramp profile generator as well as an adaptable microstep sequencer with microstep RAM table. Advanced stop- and reference switch handling allows for precise and fast referencing as well as on-the-fly position checking. Automatic motor current control gives high motor dynamics while saving energy. The interrupt output can generate precise position pulses.
The TMC428 connects to the TRINAMICs SPI™ drivers (TMC236,TMC239,TMC246 and TMC249) or to Step-/direction drivers. A second SPI™ interface allows communication with a host microcontroller. The host microcontroller just needs to do high-level control tasks, e.g. giving the command: Drive motor 2 to position 1000. The TMC428 then automatically calculates the motion ramp based on velocity and acceleration parameters.
The TMC423 adds encoder functionality as well as step- direction impulse forming to the TMC428. Evaluation Boards, application notes, spreadsheets for parameter calculation, C code examples and schematics are available in order to support short design-in times.
TMC 428 - The small but intelligent Controller:
* Miniaturized low-cost 3 axes motor controller
* High-performance micro stepping
* SPI interface with easy-to-use protocol
* On-the-fly alteration of position set point

TMC454
Description
1-axis stepper motion controller with S-ramps and encoder feedback
The TMC454 is the direct successor of the TMC453 and is 100% software compatible.
The TMC454 is a high-end motor controller for all common 2-, 3-, and 5-phase stepper motors. It provides encoder feedback for high reliability or high position resolution drives. A large set of motion control features is included on this IC. The various function blocks are hardwired and „ready-to-use“. All processes can be serialized using the instruction based interface. A complete linear & S-shaped ramp generation unit is integrated within the TMC454. All dynamic parameters can be adjusted for a given application in a very broad range. The CPU is relieved from all time critical tasks like ramp calculation or microstep generation. Thus CPU and software engineer can focus on higher level motion control
jobs. In many applications, the TMC454 reduces the time time-to-market, and it saves costs for software development and hardware engineering. The TMC454 turns stepper motors into easy to use peripherals!
The TMC454 is upwards function compatible to its predecessor TMC453.
