How does nano-CT differ from micro-CT?

Nano-CT uses the same computed-tomography principle as micro-CT — reconstructing a 3D volume from many X-ray projections — but achieves sub-micron resolution, roughly an order of magnitude finer than micro-CT's micrometer-scale resolution, at the cost of a smaller field of view and a smaller maximum sample size.

What sample size limitations does nano-CT have?

Because resolution and field of view trade off directly against each other in X-ray tomography, nano-CT samples are generally limited to a few millimeters or less in size — larger samples that need this level of detail typically require a smaller sub-sample to be extracted first.

What kinds of features can nano-CT resolve that micro-CT cannot?

Nano-CT can resolve fine internal nanostructure such as sub-micron porosity, thin coating layers, nanoparticle distribution within a matrix, and delicate internal architecture that would appear as a single blurred region under micro-CT's coarser resolution.

Is nano-CT a replacement for electron microscopy?

Not typically — nano-CT's resolution, while much finer than micro-CT, does not reach the nanometer-to-atomic resolution of TEM or SEM. Its advantage is non-destructive, fully three-dimensional internal imaging without sectioning, which electron microscopy generally cannot provide for an intact sample.

How long does a nano-CT scan take compared to micro-CT?

Nano-CT scans generally take longer than micro-CT, since achieving finer resolution requires collecting more projection images and longer exposure times per projection — actual scan time depends on the sample, the resolution required, and the level of detail needed in the reconstruction.

私たちの違い

スペクトルだけをお渡しすることはありません。お渡しするのは解釈です。

どの検査機関でもピークと数値は返せます。私たちの報告書はデータを読み解きます。私たちが提供する価値を決定づける3つの違いを、匿名化した実際の事例で以下にご紹介します。

複数の分析技術を、1つの統合された報告書に

バラバラの5つの報告書をお渡しすることはありません。すべての分析技術の結果を突き合わせ、各シグナルを他と照合したうえで、単一の解釈にまとめ上げます — データの山ではなく、答えにたどり着くためです。

汚染調査 — 異物の由来を特定し追跡する。
性能劣化 — ロットが想定外の挙動を示す理由を説明する。
