The minispec LF50H Body Composition Mice Analyzer:
Horizontal 7.5 MHz TD-NMR system on cart for whole-body composition analysis (BCA) of rodents, like mice. Measurement is conducted with the animal fully awake adopting animal care. No need to anesthetize animal. Recommended for laboratory animals with up to ca. 60 g in weight. Key features are:
• High repeatability and reproducibility
• Short measurement time
• Easy-to-use front-end software
• Easy-to-follow and extendable calibration software tools (auto-optimization)
• Determination of fat, lean, free water etc. in mice
• Also recommended for biopsies and tissue samples.
The minispec mq-Series/LF-Series are flexible TD-NMR Analyzers and can potentially also be used for other applications, of course depending upon system configuration.
the minispec LF50H Body Composition Analyzer comes on a cart (included) and consists of:
minispec mq control unit (NF series), E1452120_01, with broad band transmitter, consisting of:
• Electronics Unit Housing: EMI-shielded, CE-conform, closed housing, maintenance-free, air-cooled, wide-line power supply, LEDs for convenient diagnosis (power-on, connection).
• Central Processor Unit (CPU): Embedded CPU with real-time processor unit, dynamic RAM and Flash-ROM for firmware. 100 Mbit Ethernet adapter to host PC. Fully featured remote control via minispec software.
• Direct-Digital RF Frequency Generation and Pulse Programmer: Frequency range, 5 - 65 MHz (tested and validated on NMR frequencies as supplied by Bruker) with 1 Hz stepping, resolution better than 1 ppm. Pulse programmer, 20 ns timing resolution, virtually unlimited number of pulse generations. Phase resolution better than 0.2°
• Receiver/Analog Digital Converter (ADC): Digital quadrature receiver, variable gain and variable digital filter. Highly linear 14bit digitizer with up to 12.5 MHz digitization rate (dwell time 80 nanoseconds). 2 x 32k Number of complex data points.
• Broad Band Transmitter: Broad band transmitter with 7.5 MHz: 250 W; 10 MHz: 300 W; 20 MHz: 300 W; 40 MHz: 300 W; 60 MHz: 250 W output power.
• Software included: the minispec software for data acquisition for Microsoft Windows including daily check, update setting, status logging, autoprobe recognition of plug-and-play probes, and suitable minispec application pools, fitting to the proposed minispec hardware.
Digital RF pulse attenuation:
• Attenuation of the amplitude of the RF-pulse(s).
• Dynamic range of over 70 dB (factor of 10E7).
Recommended for R&D applications.
• Can only be ordered in combination with the broadband transmitter being part of the control unit with broad band transmitter.
• The minispec digital RF pulse attenuation is integral part of the minispec installation and can be activated by a licence key.
minispec mq7.5 magnet, 0.17 T, 7.5 MHz, 62 mm air gap, in cart with turning mechanism, consisting of:
• Rotating-base, large-air gap, high field combination at 7.5 MHz, 0.17 Tesla minispec magnet system with an exceptional air gap of 62mm. Magnet system of the minispec LF50H BCA system. Compatible with proton probe assemblies H7.5-50-562AD, H7.5-50-62ADO. Magnet unit can be rotated by 90° to enable vertical and horizontal sample access and in combination with the open bottom probe assembly H7.5-50-62ADO pass-through access.
• magnet temperature control with digital PID control, pre-selection of magnet temperature (range 35 °C to 45 °C). Factory Setting is 37°C. Temperature stability better than 0.01 °C. Fast magnet pre-heat mode for rapid warm-up.
• EMI-shielded, CE-conform Housing with zero maintenance. Built-in sample storage compartment (up to 18 mm sample diameter) and LEDs for convenient diagnosis (on-temperature, connection).
• optical sample detector, based on optical technology for reliable and interference-free sample-in triggering and automati
