Ultra-High-Purity Analytical Reagents
TAMAPURE-AA Series
The "TAMAPURE-AA" series is an ultra-high-purity analytical reagent developed with the goal of achieving a “World of ZERO impurities”. The TAMAPURE-AA series is used across a wide range of scientific and technological fields such as electronics, environmental science, biochemistry, and medicine.
TAMAPURE-AA Series Features
The greatest feature of the TAMAPURE-AA series is its world-class purity, with metal impurity levels below ppt (pg/mL). Another major feature of the TAMAPURE-AA series is its exceptional consistency in quality. Through our proprietary manufacturing and packaging technologies with rigorous quality control, we have significantly enhanced the uniformity of quality between production lots and between individual containers.
Applications
The TAMAPURE-AA series is mainly used as blank and pretreatment reagents in ultra-trace analysis. By using the TAMAPURE-AA series, sample contamination is prevented during pretreatment, reducing blank values and greatly improving analytical sensitivity and accuracy.
Example applications:
- Quantitative analysis of ultra-trace metal impurities in high-purity semiconductor chemicals
- Quantitative analysis of ultra-trace metal elements on silicon wafer surfaces
- Quantitative analysis of ultra-trace metal impurities in diluted sample
- Quantitative analysis of ultra-trace metal impurities in water quality samples

TAMAPURE-AA Ultrapure Water
In trace analysis, ultrapure water is used for cleaning devices and containers as well as for sample dilution.
Using TAMAPURE-AA ultrapure water that metal impurities below ppt levels, reduces blank values and yields more reliable analytical results.
- Metal impurity levels are kept below 10 ppt.
- Please open it and use it in a clean area of Class 4 or higher.
- Packaging: 500 g
TAMAPURE-AA TMAH
TMAH, short for Tetramethyl Ammonium Hydroxide (chemical formula (CH3)4NOH), is a strongly alkaline aqueous solution. It is very effective for the quantitative analysis of volatile elements in acid pretreated samples. Compared with commonly used for alkali fusion reagents such as NaOH and KOH, TMAH has the advantage of exhibiting minimal matrix effects.
- Metal impurity levels are kept below 1000 ppt.
- Please open and use it in clean areas such as cleanrooms.
- Packaging: 500 g
Wafer Surface Analysis Scan Solution
TAMAPURE-AA SSX
The TAMAPURE-AA SSX is a scanning solution developed for wafer surface analysis (pre-treatment by the VPD method → dissolution by the DADD method → analysis by GF-AAS, ICP-MS, TXRF). It was developed to meet demands for improved reliability in ultra-trace metal analysis on wafer surfaces and to increase efficiency of cleanroom operations.
・SSX is an aqueous mixture of 2% hydrofluoric acid and 2% hydrogen peroxide.
・Metal impurity levels are kept below 10 ppt.
