What’s on the Calibration poster
A 6-row table: Term · Is.
Types of standard and their role.
- Primary standard — Pure, stable, known formula, high Mr
- Standard solution — Known concentration, made from a primary standard
- Calibration curve — Signal plotted against known concentrations
- Internal standard — Added to every sample to correct for variation
- Blank — Everything except the analyte
- Certified reference material — Independently verified composition
Sodium carbonate is a good primary standard: pure, stable, non-hygroscopic and with a high relative formula mass.
Questions about the Calibration poster
- What’s on the Calibration poster?
- A 6-row table: Term · Is. Types of standard and their role.

- Who is the Calibration poster for?
- Calibration belongs to the Chemistry section rather than to a school year, because physical science is not something one grade owns. Anyone learning analytical can pin it up — a beginner, a student mid-course, or someone revising years later.
- When should you use the Calibration poster?
- Every quantitative measurement needs a standard of known concentration. A wall chart earns its place by being glanceable from where the work is happening, so Calibration belongs on the wall where that physical science work actually happens, within glancing distance, rather than filed away.
- What other posters go with Calibration?
- Quality Control, Indicators and Chromatography Methods sit alongside Calibration in the Chemistry section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Quality ControlIndicatorsChromatography Methods
- Is the Calibration poster free to download and print?
- Yes. Calibration downloads as a free PDF with no account, no email and no watermark, like everything else in the Chemistry section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
- What size does the Calibration poster print at?
- Calibration is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Calibration loses nothing.Printing guide
