    Wipe Test Library

    The Multi-Wiper is designed to allow you to customize the software to suit your individual needs. Up to 16 wipe sets may be named, each with up to 10 locations per wipe set. Furthermore, you can even select which isotopes from the Isotope Library to look for in an particular location. Individual trigger levels may be set, depending on weather it is a patient access area or not. All in all, an incredible amount of customization is possible, all designed to make day to day wipe testing fast, simple and effective.

    Keep it simple. Can you just walk up to the instrument and run a generic wipe? Absolutely! That is why we pre-programmed GENERAL into the Library. Choose General, and run a wipe test. The counter reads in a wide window and identifies any isotope windows which exceed the preset trigger. The results are recorded as wipe#1, wipe#2, etc. Nothing to re-program-just count and report.
    Isotope Library

    Up to 30 different isotopes may be programmed into the Multi-Wiper. The counter comes pre-programmed with 17, which may be modified or deleted by the operator. Customize the window settings as you wish. Once the efficiency is either calculated from a known source, or entered manually for a given isotope, wipe test results will always be reported in DPM.

    The detectors used in the Multi-Wiper are elongated. This design adds additional crystal mass below the well. This extra mass improves the "stopping power" for higher energy isotopes, and makes it easier to count higher energies (such as PET) effectively.

    What about crosstalk at higher energies? The Multi-Wiper has a very unique feature called E-Lead. E-Lead eliminates crosstalk between wells when high energy isotopes are counted. By using E-Lead, counting even PET isotopes is not a problem.
    System Diagnostics

    The Multi-Wiper has the ability to test many of its parameters. This feature can be quite helpful in identifying potential hardware problems. Chi Square and FWHM tests check the system's detectors and counting circuitry. System RAM test checks the memory to make certain that it is operating properly.

    Auto Calibration performs a a detailed re adjustment of the entire system, this includes a Detector Gain Adjustment, High Voltage Setting and Lower Level Detector setting. By using the Auto Calibration detector aging and gain shifting can be compensated for giving your counter a long maintenance free life.
    In-Vitro tests

    The Multi-Wiper is programmed to run a variety of common in-vitro tests. From Schillings to GFR, the software does the calculations automatically, so all you need to do is count and report. Put away the calculator and let the Multi-Wiper do the work!

    The Multi-Wiper generates comprehensive easy to read test reports. These test reports may be customized with the patient's data, by automatically accessing the patient library.
    Patient Library

    The Patient Library is designed to store up to 32 patients. Once these patients and their related information have been keyed in, this data works in harmony with the In-Vitro Test section of the software.

    When you begin to run a test, such as schillings, the counter software will ask if you wish to use a patient from the Library. You may then select which patient to use, or by-pass the Library. If you choose a patient from the Library, their data will be automatically entered into the test report.

    If you choose to by-pass the Library, the report will print out blank lines next to the various information fields, such as patient name. The blank lines are designed to allow you to hand write the information onto the report.

    Wiper Gold LSV Single Well Wipe Test Counter
    Optional - Detector shield lid allowing for tubes up to 3.6" (91.5mm)
    Optional Printer

    Suitable for PET facilities (Na22 shown; 511 KEV peak)
    With the resolution power of 4096 channels, isotope identification is easy. No other wipe test counter offers a clearer spectrum or better identification. No other well counter offers better energy linearity for accurate spectral plotting. No other counter has AutoSpect automatic efficiency determination for any isotope, without the need for a calibrated source.
    Loads of features are great--but if they are difficult to use, will you ever take advantage of them? With the WiperLTI100-1, LTI has taken great care in making their software as easy to use as it is feature-rich. Using the graphical display and full alphanumeric keypad, navigation and data entry are easy. A menu-driven interface, with simple shortcuts to common functions, makes this software easy for a new user to walk right up to the unit and run wipes.
    Wipe test and Schilling reports are clear, concise and logical. All relevant data is easily identified. Pass/Fail based on individual trigger levels is clearly displayed. Location, name, date/time, trigger, isotope/window, CPM, DPM, Beq, etc. are logically arranged for easy reading. Additionally, calibration and background reports are just a keystroke away. Reports are available on-screen, via the optional printer, or through download to a computer. Flexibility and logical design make it simple to get the information you need with minimal effort.

           More infomation on the included AutoSpect ™ Efficiency Correction.       
    Laboratory Technologies, Inc! Efficiency Correction

    Until now, there have been two basic ways to determine DPM for wipe test samples:

    I. Calculate the efficiency of the counter by using a known, calibrated source of the isotope you are looking for (or use a "mock" standard).

    II. Enter an efficiency value based on a "best guess".

    While either of these methods will produce results, keeping calibrated sources for every isotope you use in the department is expensive, and checking them regularly is time consuming. The second method of estimating the efficiency is questionable, and not accepted by all regulatory agencies.

    Laboratory Technologies, Inc. now offers you a third option; AutoSpect. Built into every Wiper, Multi-Wiper and Multi-Wiper HE, AutoSpect provides an accurate method for reporting wipe test results in DPM, without needing calibration sources.

    AutoSpect uses known detector efficiency values at various levels across the energy spectrum. These values account for crystal thickness and well geometry among other factors in order to maximize accuracy. Armed with this data, the Wiper and Multi-Wiper automatically determine the detector's efficiency at any point on the energy spectrum. At the same time, it allows the instrument to count and display spectra as they truly should appear, unaffected by lower detector efficiency at higher energy.

    If you choose to use AutoSpect, the photon abundance can be entered for each isotope in the library. Each isotope is unique, so it is important to enter the proper number. The instrument comes pre-programmed with abundance factors for the most common nuclear medicine isotopes. You can add or adjust any values you wish.

    AutoSpect applies the crystal efficiency, determined by your isotope window, as well as the photon abundance. Your Wiper or Multi-Wiper automatically converts CPM into DPM for all wipe test samples run with an AutoSpect enabled isotope.

    AutoSpect makes for truly simple, accurate and automatic wipe test reports sure to please your regulatory inspector or RSO. Best of all, it is already set up in the system; the user needs to do nothing more than count their wipes.
