QCM922A(QCM system) The successor of QCA922 high speed ＆ high sensitivity QCM QCM922A is the successor of QCA922 and can be simultaneously measured a small mass change as resonance frequency and the viscoelastic change as resonance resistance and is corresponding to the measurement of the frequency characteristics of admittance. QCM922A is capable of high sensitivity of up to 30MHz and high-speed of up to 10msec. Application examples •Measurement of biopolymer interactions, such as protein •Real-time monitoring of the formation of high molecular and decomposition •Evaluation of a lithium ion secondary battery with EQCM •Gas analysis, such as humidity and smell substance •Quantitative evaluation of the detergency in surfactant •Film thickness measurement in the plating •Analysis of structural change by the measurement of the frequency characteristics of the admittance Example of QCM922A System Configuration Flow Cell system QCM922A-020, QA-CL6/ CL6PK/ CL7 PC, WinQCM, Peristaltic pump EQCM system QCM922A-EQCMBASE, PC, Potentiostat/Galvaostat BNC cable, Stand, Lab jack Specification □QCM922A-020: Main unit Item Description Simultaneously Resonance frequency & Measuring item resistance or Admittance frequency characteristics Resonance Resolution: 0.01 Hz frequency Range: 5 MHz to 30 MHz Resonance Resolution: 0.01 Ω resistance Range: 1 Ω to 10 kΩ Admittance frequency Frequency range: 4 MHz to 30 MHz characteristics Range: ±10 V(14bit) ΔF analog output Scale: ±100 Hz to ±500 kHz Range: ±10 V(14bit) ΔR analog output Scale: ±10 Ω to ±10 kΩ Analog input 2ch, Range: ±3, 6, 12 V(14bit) Gate time 10 ms/ 20 ms/ 100 ms/ 1 s/ 10 s Display 20 characters 4 lines OLED Interface USB 2.0 Input power source AC 100 to 240 V, 50/60 Hz Power consumption Max. 25 VA Dimensions 162 x 160 x 95 (WxDxH)[mm] * Weight Approx. 1.3 kg Operation environmental 5℃ to 40 ℃(non-condensing) temperature Compliant CE marking (EMC, low-voltage directive) standards QCM922A-020 contains main unit and QCM922A-100 □QCM922A-100: QA-CL Adapter Cable Item Description Material Case:PVDF Connector:LEMO® plug(Male) Connection cable Cable:Coaxial multi cable:about 1.0 m Connected to the working electrode of Potentiostat/Galvanostat internally Working(W) connected through a low pass filter and a terminal measurement electrode surface of the quartz resonator Dimensions 24 x 40 x 15 (WxDxH)[mm]* Weight Approx. 130 g(including cable) Operation environmental 5℃ to 40 ℃(non-condensing) temperature □9MHz AT-Cut Quartz Crystal Resonator QA-A9M-series Item Description Au, Pt, Ag, Al, C, Cu, ITO, Mo, Ni, Si, SiO2, SUS304, Ti, etc. Electrode material 300nm of electrode material is sputtered onto a Ti film groundwork Electrode area 5mmφ □Dip Cell: QA-CL3 Item Material Dimensions Usage Description Main body: PTFE, PVDF O-ring: Viton® 25.5 x 20 x 12 (WxDxH)[mm]* Solution or air □Well Cell: QA-CL4/ QA-CL4PK Item Description Main body: PTFE, PVDF(QA-CL4) Material PEEK(QA-CL4PK) O-ring: Viton® Dimensions 25.5 x 20 x 12 (WxDxH)[mm]* Capacity Max. 750μl Cell is filled with solution or CL4 and CL4PK Usage are connected with RG100(Cell of EQCM) □Well Cell: QA-CL5 Item Description Main body: VC Material O-ring: Viton® Dimensions 25.5 x 20 x 12 (WxDxH)[mm]* Capacity Max. 250μl Usage Cell is filled with solution □Flow Cell: QA-CL6/ QA-CL6PK/ QA-CL7 Item Description Main body: PTFE, PVDF(CL6)/ Material PEEK(CL6PK)/ VC(CL7) O-ring: Viton® Dimensions 28.0 x 20 x 12 (WxDxH)[mm]* Capacity 90μl Usage Cell is flowed with solution by the pump * without a projection part Product names in this paper are trademarks or registered trademarks.
