MALDI TOF mass spectrometers (matrix-assisted laser desorption/ionization/time-of-flight) are amongst the most popular mass spec instruments in biology. They combine two technologies, the “soft” MALDI ionization source and the TOF mass analyzer. The latter measures an ion’s mass-to-charge ratio (m/z) by measuring the time it takes to reach a detector. The former volatilizes and ionizes those molecules using a laser, a target, and an organic compound called a matrix. In MALDI, a sample (for instance, a collection of tryptic peptides) is mixed with matrix, spotted and dried (crystallized) on the surface of a metal target plate. Upon irradiation with laser light, the matrix absorbs the energy and converts it to heat, which then causes the sample to ionize and explode off the plate into the mass analyzer. MALDI TOF mass spectrometers come in two basic flavors, MALDI TOF MS and MALDI TOF/TOF MS; the latter enables tandem MS (MS/MS) studies.

| Description | Certain microorganisms can cause severe diseases and considerable damage, and need to be identified quickly and reliably. The easy-to-use AXIMA-iDPlus Microbial Identification System is the ideal tool to address these concerns. With AXIMA-iDPlus, cultured microorganisms can be directly applied to Certain microorganisms can cause severe diseases and considerable damage, and need to be identified quickly and reliably. The easy-to-use AXIMA-iDPlus Microbial Identification System is the ideal tool to address these concerns. With AXIMA-iDPlus, cultured microorganisms can be directly applied to the MALDI sample target and introduced to an AXIMA series MALDI-TOF mass spectrometer to revolutionize the daily routine in analytical and diagnostic laboratories.
Fast Response, Outstanding Recovery Rate
AXIMA-iDPlus can identify 380 clinical research samples within 5 hours in the high-throughput mode, less than one minute per sample. The results appear in a comprehensible spreadsheet format, exportable to common data processing software.
Gram-positive and gram-negative bacteria, yeast, fungi and spores are identified based on their characteristic MALDI-TOF MS fingerprints with up to 98% recovery rate down to sub-species level.
Substitutes Biochemical Standard Methods
No pre-selection of analytical methods is required; hands-on time is reduced and costs are cut dramatically.
Wide Range of Applications
AXIMA-iDPlus covers a wide range of applications in a number of industries, including diagnostics, pharmaceuticals, healthcare and food. Examples include:
- Diagnosis of human and veterinarian infectious pathogens
- Drug discovery process
- Culture collections
- Food and beverage manufacturing processes
Complementary Method
Designed for medium to high-throughput identification, AXIMA-iDPlus can be easily integrated into automated laboratory environments and any LIMS....

Used in conjunction with the compact benchtop MALDI-TOF 8020/8030 systems, it provides a welcoming platform by combining the ease of MALDI analysis with extremely intuitive software in an all-inclusive imaging kit. The system can serve as an ideal teaching tool to introduce users to MALDI imaging. In addition, it offers a low-cost entry point to users who would like to see what MALDI imaging can offer for their workflow.
The benchtop systems are equipped with a fast sample stage and quick-load technology, which enable a short time-to-analysis while delivering low associated overhead costs with a long-life fast laser (200 Hz), the longer-life AeonDetectorTM and self-cleaning ion optics based on the Shimadzu TrueCleanTM technology.
The Benchtop MALDI-TOF Imaging Kit is a value-added package to complement existing and new users of the MALDI-8020 or MALDI-8030, expanding the already versatile capabilities of these systems. The kit includes everything users need to begin imaging experiments on their MALDI-8020 or MALDI-8030 system, including:
- Custom ITO-coated glass slides
- New custom glass slide holder
- Metal slides for those who prefer a reusable slide option
- Mask to facilitate sample mounting and to shield regions of the glass slide during matrix deposition
- Carrier to aid optical scanning
The MALDI Solutions IonView software (included in the kit) provides an easy workflow for the routine processing of MALDI images such as snapshots, overlays, and displays of regions of interest and pixel spectra.... Read More | Inquire |
