Product Portfolio

  • Pre- Configured Spectroscopy Solutions

      • Absorbance SPEC Pack

      • There are many ways to perform Absorbance measurements, either with the traditional cuvettes, probes that can be used in reaction vessels or flow cells. With Sarspec’s spectrometers the absorbance measurements can be made either with speeds up to 2857 spectra per second, optical resolutions better than 0.1 nm in a detection range from 180 to 1100 nm. The spectrometers used in these configurations have extra flexibility and robustness (with no moving parts) when compared with regular spectrophotometers and allow full spectra acquisition with time resolution down to 350 µsec - ideal when performing Absorbance vs. Wavelength vs. Time measurements.

        As full pack for Absorbance measurements all SPEC Packs are configured with wide range UV/Vis/NIR spectrometers, Light Source DW (Deuterium Tungsten) and different accessories depending on application. The available pre-configured solutions from Sarspec for Absorbance are:

          • Flourescence SPEC Pack

          • When performing Fluorescence measurements, in most applications, sensitivity is a key factor and at Sarspec we take it seriously. The configurations offered takes the sensitivity to a new level by using back thinned detectors with quantum efficiency up to 78% and 1 mm height pixel elements combined with large 200 µm slits and collecting lens. This combination makes all the difference in the detection of fluorescence signal.

            Combining the detector with high power LEDs from LS-LED Light Source - with easily interchangeable LEDs - customers can have a sensitive and flexible solution for a fraction of the cost of a traditional spectrofluorimeter. For UV excitation we recommend the Xenon Flashlamp Light Source LS-XeF.

              • Flourescence SPEC Pack CUV

              • This is the most sensitive configuration available, mainly due to the sensitivity of the back thinned CCD array with high quantum efficiency (up to 78%) together with 200 µm slit, and collecting lens for the detector.

                Also, the high power LEDs from the flexible LS-LED Light Source - where many different excitation wavelengths can be used by simply changing the LED slide - contributes greatly for the final sensitivity. In this configuration the sample holder takes an important role on the sensitivity and flexibility of the solution. Sarspec’s Multipurpose Cuvette Holder uses 12.7 mm diameter lens for large sample area illumination/collection and reflecting mirrors to employ all radiation available and supports a wide range of filters easily interchangeable.
                 

              • Flourescence SPEC Pack CUV Basis

              • With great sensitivity in the Visible range, the SPEC PACK CUV BASIC is the most affordable solution for fluorescence available.

                Using a SPEC STD FL spectrometer with 200 µm slit and collecting lens for greater sensitivity, the LS-LED Light Source with high power LEDs and where due to the LED slide principle can easily change the excitation wavelength, large core optical fibers and the flexible cuvette holder CH.

              • Flourescence SPEC Pack XEF

              • When high power excitation in the UV is required the light source is normally quite expensive. An affordable solution for users that want to work with UV excitation and obtain good results in Fluorescence is to use the Xenon Flashlamp Light Source LS-XeF from Sarspec. With it, it's possible to obtain great fluorescence results with high flexibility.

                The full configuration includes the high sensitivity spectrometer SPEC SENSE+ UV/Vis with a back-thinned CCD array with 2048 elements and great quantum efficiency in the UV Range, optical fibers with 1000 um core diameter (50 cm), the multipurpose cuvette holder CH-MP with filter slots, large lens and signal enhancing mirrors (CH-MP-EM).

              • Flourescence SPEC Pack FLOW

              • In the Fluorescence SPEC PACK FLOW one can combine the flow analysis technique with fluorescence measurements making it a powerful tool for research in Biology and Chemistry.

                The configuration of this solution consists on the highly sensitive SPEC SENSE+ FL spectrometer using a back thinned CCD (Q.E. = 78%) with collecting lens and 200 µm slit. The LS-LED light source with high power LEDs (where due to the cassette principle can easily change the excitation wavelength) the Flow Cell FCFPE or FCFSS with sapphire windows and SMA connection completes this solution.

                                    • The increasing market for Near Infrared Spectroscopy in the last years due to industry needs in raw material classification, polymer analysis, moisture quantification, saturated fatty acid identification among others lead to the development of different instrumentation, mainly for miniaturized solutions that can be portable, robust and easily integrated in an industrial environment.

                                      One of the biggest issues with NIR spectroscopy was the cost of the multi element detectors which made the investment for an NIR Spectrometer prohibitive for some industries. With the innovative design of SPEC NIR that uses single element detectors, Sarspec is able to offer an affordable solution ideal for transmission measurements with high stability and robustness.

                                      Also, the SPEC NIR is it the only miniaturized fiber optic spectrometer with the capability to use Silicon and InGaAs detectors for a detection range from 660 to 2400nm with the best optical resolution. This is possible due to the use of ultra fast periodic micro electectrical-mechanical mirrors with scan speeds up to 4ms and two single element detectors.

For this to occur, the light emitting element must be placed at the focus of the lens.On the other side, if the incident light is already collimated the collimating lens will focus the light in its focal distance.

                                                                            All of our collimators covers the UV-VIS-NIR range and have a two-part housing of aluminium, a screw to adjust the position of the SMA connector, allowing users to adjust the focus.

                                                                              ​• Anodized aluminium housing

                                                                                  • Reflectance Standards

                                                                                  • Sarspec has available two types of reflectance standards, for diffuse and specular reflectance.

                                                                                    The specular reflectance type consists of a 50 mm mirror with fused silica substrate coated with Al-MgF2 for high specular reflectivity in a wavelength range from 250 to 2500 nm.

                                                                                    For diffuse reflectance all Sarspec standards use optical PTFE which consists of a pure polytetrafluorethylene (PTFE) disc with 50 mm diameter. As a result of its incomparable whiteness and purity, optical PTFE achieves virtually ideal Lambertian reflectance properties with a reflectivity coefficient of up to 98% in a broad wavelength range from 250 to 2500 nm. Aditional advantages when using optical PTFE is its high UV stability, universal chemical resistance and can be easily cleaned.

                                                                                    Sarspec offers one specular standard and three diffuse standards corresponding to reflectivities of 98%, 50% and 10%. There’s also the possibility of customization for different sizes or reflectivities.
