Various traps: these traps can be mounted on the rear panel. Some of them can be regenerated in place. The type of trap to use is application dependant. Generally speaking, a trap is used in a configuration where the bulk part of the background is vented. The trap will get the background trace resulting in a zero baseline resolved peak. They are available for H2 and O2.
Gas purifier: the GP-200 series of gas purifiers is used to generate high quality carrier gases and zero calibration gas.
Sample stream selection system. The K4000 can be fed by a MSS or an ISS. These patent pending sample stream selection systems are the best available on the market. They allow sample stream selection remotely or locally. There is no sample stream cross contamination, air diffusion or dead volume.
Proprietary column for the separation of Ar and O2. This column is used when the measurement of Ar and O2 has to be done. The plasma detector for an Argon impurity has a sensitivity of 100 ppt. The separation is done from room temperature to 50ºC. | | | Optional features
- Remote start digital input Isolated RS-232 communication ports for remote monitoring and control of the instrument
- INTERNET (Web enabled) communication (to be released). Allows to monitor or control the K4000 from anywhere around the world!
- Quick check configuration: When the background is the same as the carrier gas, this option allows a total gas purity verification as a GO-NO-GO. One sample injection is done, the G.C. column is by-passed and all impurities are injected at the same time. Based on the degree of change in the baseline, the total impurities of the gas may be evaluated. It takes less than 30 seconds to have the result. It is a useful option when troubleshooting gas distribution line integrity in semiconductor industries for example. In some cases it is possible to work with gas different from the carrier gas. Please consult factory.
Standard industrial I/O interface
Many plants still use the standard 4-20 mA output as the way to transmit a process value to a remote system. In this case, digital dry contact outputs are needed to transmit the range on which the analyzer is. All the industrial type I/O's, i.e. analog or digital, are mounted in a separate enclosure called the I/O Box. The I/O Box has its own power inlet, filter, transient protection and switch. There is a set of terminals to connect analog or digital I/O. There is a DB-15 connection cable between the K4000 and the I/O board. Moving away this type of I/O from the main chassis eliminates the possibility of interference and allows configuration tailored to specific needs. It is also possible to install the I/O Box close to remote PLC or DCS. In this case, an isolated serial communication scheme is done between the K4000 and the I/O Box.
Industrial process 4-20 mA analog output
Up to sixteen 4-20 mA outputs can be installed in the I/O Box. Each one can be associated with one impurity. For this reason they can be seen as a standard 4-20 mA representing the ppb, ppm or % of the associated impurity.
| 4-20 mA output characteristics | | Maximum load impedance: 600 ohms
Fuse protected
Transient protected
Isolated from power ground and analyzer electrical circuit
Each output is completely floating and isolated from each other
One 4-20 mA output can be programmed (user programmable) to retransmit the chromatogram instead of process value. This can be useful for remote diagnostic or to drive a separate third party integrator Analog output can be programmed to be over driven or under driven in case of system status alarm. This is a useful feature for older plants that have to be retrofitted. By monitoring remote process charts, one can know if the system is operating normally
Each 4-20 mA can be driven manually to calibrate remote monitoring system as for troubleshooting | | Digital output | | System status dry contact output: Contrôle Analytique was the first analyzer manufacturer to integrate, in all gas analyzers that we manufacture, this unique diagnostic feature. This contact will change state to indicate if there are any anomalies inside the system that can make the analyzer readings unreliable.
Remote range identification output: normally each impurity has 2 operating ranges. There is one dry contact output for each impurity to indicate on which range the impurity is being measured. Can be set to be closed or open on range 2.
Process alarm output: for each impurity, two alarm level process set points can be entered to activate their respective alarm dry contact outputs. The peak being in alarm will also be indicated on the K4000 display. | | Digital output characteristics | | Each digital output is dry contact single pole single throw (SPST), snubber protected, fused protected at maximum 1A, 250 VAC resistive load. Digital outputs have their separate terminals for each contact, no common connection between contacts.
Each digital output can be configured to be normally open (N.O.) or normally closed (N.C.) | | Digital input | | There is, as an option, a remote start isolated digital input. When proper voltage pulse is applied on this input, an injection is started. Another injection can be started only when the cycle is finished. Multiple trigging is not possible eliminating erratic functioning.
Other digital inputs can be added and configured to answer customer needs. | | Digital input characteristics | | Inlet voltage: 24 volts DC or AC
