In the fields of materials science, semiconductor manufacturing, and surface analysis, carbon film preparation is a key process for improving sample conductivity, protecting substrates, or enhancing signal detection. The GVC-3000T high vacuum thermal evaporation carbon deposition instrument, with its core advantages of efficient coating, ultrafine particles, and uniform film thickness, has become an ideal equipment for sample preparation scenarios such as EDS (energy dispersive spectroscopy), EBSD (electron backscatter diffraction), MLA (mineral dissociation analysis), and is widely applicable to other scientific research and industrial scenarios that require carbon film enhancement.
1、 Core advantage: Dual breakthrough in efficiency and accuracy
Efficient coating, finer particles
GVC-3000T uses high-purity carbon fiber as the evaporation source (optional carbon rod) and achieves precise deposition of carbon atoms through thermal evaporation technology. Its unique evaporation control algorithm and high vacuum environment (extreme vacuum)≤5E-3Pa）The synergistic effect ensures that the carbon particle size is small and evenly distributed, significantly improving the density and conductivity of the film layer, providing a stable signal basis for subsequent analysis.
Excellent uniformity of film thickness
The equipment is equipped with a sample table rotation function, combined with an intelligent temperature control system (real-time monitoring of sample temperature), which can eliminate thickness deviation during the deposition process and achieve film thickness uniformity of ≤± 5%. Both planar samples and complex structures can form carbon films with consistent thickness, meeting the requirements of high-precision analysis.
Full process automation, easy to operate
The 7-inch TFT color LCD touch screen integrates a full process control interface and supports one click start of fully automatic operation mode. Users only need to set parameters, and the equipment can complete steps such as vacuuming, evaporation degassing, and coating without manual intervention, greatly reducing the preparation cycle and lowering the operating threshold.
2、 Application area: Covering multiple analysis scenarios
The flexibility and high precision of GVC-3000T make it a core equipment for multi domain sample preparation:
EDS sample preparation
Coating non-conductive samples (such as ceramics and polymers) with carbon film to eliminate charge accumulation, improve signal intensity and resolution in energy spectrum analysis, and ensure accurate identification of elemental composition.
EBSD sample preparation
The uniform coverage of carbon film can enhance the conductivity of the sample, reduce diffraction distortion of Kikuchi lines, and assist in high-precision characterization of microstructures such as crystal orientation and phase distribution.
MLA system sample preparation
In mineral dissociation analysis, carbon film as a conductive layer can optimize the imaging quality of scanning electron microscopy (SEM), improve the identification rate of mineral particles, and enhance the efficiency of automated analysis.
Other carbon film demand scenarios
Including the preparation of transmission electron microscopy (TEM) sample support films, conductive treatment of biological samples, surface modification of nanomaterials, etc., to meet interdisciplinary research needs.
