MULTIDETEK3 User’s manual 5. Installation 5.1. Detector cautions The MultiDetek3 utilizes multiple detection techniques that have been well-established in the industry for many years, including Plasma Emission Detector (PED), Flame Ionization Detector (FID), Thermal Conductivity Detector (TCD), and others upon request. The PED operates on the principle of spectroscopic emission.
Page 16: Analyzer Application
MULTIDETEK3 User’s manual 5.2. Analyzer application The MultiDetek3 is specifically designed for analyzing impurities and samples as outlined in the instrument's specification sheet. Using this instrument with any other gas type may cause damage to the analyzer. To ensure safe and proper use, refer to the "Operating Parameters" document that accompanies the unit.
Page 17: Figure 1: Boot Up Screen
MULTIDETEK3 User’s manual Figure 1: Boot up screen 9. Before proceeding, it is essential to resolve all active alerts, except for "Flow deviation on Sample" and "Low flow on Sample". To view the list of active alerts, double-click on the red alert bar to open the alert menu. Figure 2: Boot-up alerts...
Page 18: Figure 3: Oven Setpoint
MULTIDETEK3 User’s manual Below are the principal alerts that you may encounter: Temperature deviation: This type of alert is normal during initial start-up and will typically resolve itself after a few minutes as the ovens, HCD or heated zone warm up. However, if the alert persists and no temperature change occurs, it may indicate a problem that requires further attention.
Page 19: Figure 4: Flow Setpoint
MULTIDETEK3 User’s manual Figure 4: Flow setpoint Low flow on sample: This alert will typically resolve automatically within a few minutes. During initial start-up, the sample proportional valve needs some time to stabilize. The set- point for the sample flow can be found in the document “Operating Parameters”. You can also check the sample setpoint in the settings menu (Settings>>Settings>>Flow).
Page 20: Figure 5: Operating Parameters
MULTIDETEK3 User’s manual After resolving all active alerts, except for "Flow deviation on Sample" and "Low flow on Sample", the system must purge. A partial purge will take about 2-3 hours and a good purge will take 12-24 hours depending on the system configuration. Note that for ppb systems with ranges of measurements below 1000 ppb, the purge may take 2-3 days.
Page 21: Shut-Off
MULTIDETEK3 User’s manual peak(s) fit completely in their respective window(s). If some peaks aren’t perfectly inte- grated into their respective window, restart the analysis several times. If the issue persists, it is recommended to send the machine file (.md3m) to LDetek support for further instruc- tions.
Page 22: Typical Installation
MULTIDETEK3 User’s manual 8. Put a male cap over the carrier inlet tube that was removed. 9. If the actuation gas is coming from the same source as the carrier gas, repeat steps 7 and 8 for the actuation gas inlet. 10.
Page 23 MULTIDETEK3 User’s manual higher (>99.999%). This grade is certified to have a maximum concentration of 10 ppm of total impurities. The grade 5 carrier is then purified by a filter-type heated gas purifier (LDP1000). Starting from grade 5, the outlet purity of the purifier will be 99.999999% (grade 8.0).
Page 24: Figure 6: Typical Installation
MULTIDETEK3 User’s manual Figure 6: Typical Installation...
Page 25 MULTIDETEK3 User’s manual 5.5.2. Valves actuation Separating the actuation from the reference carrier gas allows our gas chromatograph Mul- tiDetek3 to achieve better results and more stability. The reason for it is mainly because of pressure changes when valves are actuating during cycles. This causes an impact on the carrier gas pressure and results in baseline fluctuation which can affect the response of the detector.

This feature is only required when O2 is measured at the ppm/ppb level and is used to keep our system saturated with Oxygen. In chromatography, it is well known that oxygen is adsorbed by the Molecular Sieve and the porous polymer-type columns used for separating and measuring trace oxy- gen.

Page 30: Hardware Description
MULTIDETEK3 User’s manual 6. Hardware description The MultiDetek3 has major components included in its chassis. This section will describe each component that can be replaced for maintenance or upgrade. 6.1. Detectors The PED detector module is a 155 mm (6.1”) x 82 mm (3.22”) x 63 mm (2.48”) box that contains all components needed to proceed to accurate measurement.
Page 31: Motherboard
MULTIDETEK3 User’s manual 6.2. Motherboard This I/O board controls all components inside the analyzer (flow, detectors acquisition, temperatures, etc.). When replacing this motherboard be sure to avoid any electrostatic contact. The motherboard conception is modular, which makes it easy to replace even on the field. Flow sensors for the carrier and sample, the 4-20 mA modules and the microcontroller can also all be replaced on-site.
Page 32: Sample Gas Proportional Valve, Mini Pump And Septum Injector
MULTIDETEK3 User’s manual 6.3. Sample gas proportional valve, mini pump and septum in- jector This valve is used to control the sample flow inside the instru- ment. This is a very low dead volume valve that allows minimal purging time at start-up and is very quick for flow stabilization. This valve has been designed by LDetek to achieve good stability and the possibility of working at ppb level without contamina- tion.
Page 33: Carrier Gas Electronic Pressure Regulator (Ldepc)
MULTIDETEK3 User’s manual 6.5. Carrier gas electronic pressure regulator (LDepc) The carrier gas flow control in the MultiDetek3 is managed by a high-purity LDetek electronic pressure controller (EPC). The car- rier flow control can be mounted inline or in bypass mode depend- ing on the application.

MULTIDETEK3 User’s manual 6.7. Large 15.6’’ touch screen LCD & LDChroma+ The MultiDetek3 offers an easy and complete interface working on Windows 10 IoT. With its clear 15.6’’touch screen LCD, it allows the operator to easily navigates through the different menus. More- over, the system includes an Ether- net port for remote control.
Page 35 MULTIDETEK3 User’s manual Handling highly flammable gas like silane or any other hazardous or explosive gases re- quires a high level of safety, and it is what LDetek offers with its built-in sample purging and monitoring system inside the MultiDetek3 compact GC. This system consists of 4 steps of safety: Step 1: The sample gas flow path external to the purged box is fully welded offering no possibility of leakage.
Page 36: Bolt-On Compact Purifier
MULTIDETEK3 User’s manual 6.9. Bolt-on compact purifier A compact purifier can be bolted on the MultiDetek3 back panel. It offers the same per- formance as the standard gas purifier but with a more compact design. The maintenance is easy since the compact unit is mounted on the back panel of the MultiDetek3. The unit of- fers intelligence, and the LED diagnostic system will turn red when the unit must be re- placed.
Page 37: Ldchroma
MULTIDETEK3 User’s manual 7. LDChroma+ The MultiDetek3 system is powered by a powerful dual-core micro- controller, with one core specifically dedicated to digital signal pro- cessing (DSP). This microcontroller communicates with a 15.6-inch touchscreen panel PC that runs on the Windows 10 operating system. The system is designed to offer users a user-friendly and comprehen- sive interface called LDChroma+.
