Raman SERS Wavelet
|
 |
|
AU Nanorod Array Chips and Plates for Signal Enhancement
Surface Enhanced Raman Scattering (SERS) is a powerful technique for the detection, identification, quantification and structural studies of minute amounts of samples in materials research, surface science, medical diagnostics, biophysics etc.
SERS greatly enhances the Raman signal from sample molecules adsorbed on noble-metal surfaces possessing nano scale roughness.
Intensity enhancements of approx. 104 up to 106 can be obtained routinely on gold surfaces.
Specifications
- Active Surface: Au
- Active Area Chip Dimensions: 5mm x 7mm or 3mm x 4mm
- Plate, External Dimensions: 76mm x 26mm (glass slide)
- Recommended Excitation Wavelength: 633nm, 785nm (recommended), 830nm
Benefits
- Highly reproducible and ultrasensitive measurments with your Raman system
- Ultrasensitive detection and characterization of extremely low concentration of analytes
- Enhancement level sufficient for Raman single molecule detection
- Trace-level analysis and identification of organic and inorganic compounds and contaminants
- Analysis of analytes at low concentration in a liquid or liquid segmented microfluidic system

μ Contact Pressure Monitor
|
 |
|
Controls the pressure applied on the ATR crystal during sample analysis
For ATR measurements the pressure is a very significant issue:
Too much pressure and either the sample or the ATR crystal will crack, too little pressure and there is no good contact between the ATR crystal and your sample.
With the μ Contact Pressure Monitor you can set an alarm at a specified pressure.
So while you gradually increase the pressure to obtain a good ATR spectrum, the alarm will be triggered as soon as you reach your pre-specified pressure limit.
Like this you can apply the desired maximum pressure on the sample for obtaining a high quality spectrum without breaking your ATR-crystal.
Features
- Easy handling & mounting
- Universal use with most FTIR –Microscopes
- Can be combined with the MircoVice-Mini for additional ease of use
- Standard 25x27mm back plate of MicroVice-Mini for easy mounting on most microscope
Benefits
- Controlled pressure exertion on sample and ATR-objective
- Acoustic signal prevents applying excessive pressure
- ATR objective and sample are protected efficiently against breaking
- Error measurements resulting from high pressures are eliminated
- Multiple samples can be measured at a specified pressure setting, thus speeding up the processing of sample

Diamond EX-Press Compression Cell
|
 |
|
With this compression cell you can easily flatten and thin materials to an ideal thickness for transmission analysis
The sample is simply compressed between the diamond windows by turning thumb screws until the sample is thin enough for the beam of the spectrophotometer to penetrate.
The Diamond Cell simplifies sample preparation of samples, which are difficult to manage by other techniques:
Excellent for analyzing hard materials such as minerals, rubbers, plastics, polymers and also pharmaceuticals. They can be compressed, crushed and flattened to a uniform thickness for IR measurements.
The total cell thickness of 9.5 mm provides smallest working distance for use with microscopes.
- Large clear aperture (1.6 mm or 2.0 mm)
- Universal use with FTIR-Spectrometers & FTIR –Microscopes
- Two type IIa single crystal synthetic diamonds
- Standard 2”x3” back plate fits all spectrometers
- To use without beam condenser
Benefits
- Simplified sample preparation
- Multifunctional use with spectrometer and/or with IR-Microscope
- Minimal interfering absorption bands
- Maximum throughput to the detector without detection saturation
- Easy to assemble and clean

Mini Plane - Sampling Knife
|
 |
|
Easily shave off surfaces into thin samples for microanalysis  Proper sample preparation tools are a requirement for any microscopy lab. This is especially true for those performing FT-IR analysis where the sample must be between 5 and 20 microns in order to provide the desired transmission.
The Mini-Plane enables you to shave off the surface of a material such as a polymer and cut a controlled and consistent sized slice of uniform thickness, optimized for measurement.  Features - Adjustable blade depth & cutting angle
- Available with choice of blades: Single Crystal Diamond (cutting width 0,7 mm) or Carbide Steel Blade (cutting width 1,5 mm)
- Ergonomic wooden grip
- Patented design
Benefits - Excellent control and reproducibility of sample thickness
- Precise depth control
- Reduced mechanical damage to specimen
- Allows you to produce sections of various thickness with the same knife
- Easy to clean
