# Krause Analytical

**Status (2026-04):** Active
**Location:** Laboratory at **8711 Burnet Road, Austin, TX 78757**. Mailing address at **8127 Mesa Drive, Suite B-206, Austin, TX 78759**. Both confirmed via krauselabs.com/about and the Contract Laboratory Network feature page (2026-04-23).
**Founded:** Krause Analytical entity itself does not publish a founding date; Mark Krause has been "in analytical testing since 1976" (>45 years per the bio).
**Principals:** **Mark Krause** — Laboratory Director / Principal Scientist. **B.S. Chemistry, Texas Lutheran College (1978); graduate studies in chemistry at UT Austin (1978–1980); >45 years experience.** **No PhD listed.** Concurrent / predecessor role: Technical Director & Owner, **Austin Analytical, LLC** (visible on LinkedIn and RocketReach — same individual operates two related entities; relevant for trust-attribution work since Krause is Finnrick's largest contributor by test volume). No other staff publicly named on krauselabs.com.
**URL:** https://www.krauselabs.com/
**Specialisation:** Contract R&D and analytical testing — small, minority-owned. Peptides, hemp/cannabis, food, supplements, pesticide screening, BPA/BPS, batch release, import-detention analysis.

By test volume, Krause Analytical is Finnrick's dominant partner — **3,836 of 6,813 tests (56.3%)** as of 2026-04-22. Same-city colocation with Finnrick HQ (both Austin, TX) is likely load-bearing for the partnership. Methodology answers exist behind a scanned-image PDF (`peptide_reproducibility_questionnaire_krause.pdf` on finnrick.com) but the PDF is image-only and returned binary corruption on WebFetch during round 1; the human-readable text has not been extracted in this research corpus.

## Instruments (with citations)

| Model / class | Type | Source |
|---|---|---|
| GC-MS | Gas chromatography – mass spec | https://www.krauselabs.com/analytical-capabilities (2026-04-22) |
| LC-MS | Liquid chromatography – mass spec | same |
| HPLC (UV / DAD — specific detector not published) | Peptide purity quantification (inferred primary workhorse) | same; also https://www.krauselabs.com/peptides |
| ICP | Inductively-coupled plasma (elements / heavy metals) | same |
| UV spectroscopy | Standalone UV instrument | same |
| IR spectroscopy | FTIR or dispersive IR (format not specified) | same |
| Fluorescence spectroscopy | Specialty / food applications | same |

No instrument makes / models / serial numbers are published.

## Assays offered

- Peptide third-party purity, potency, identity testing via LC-MS (covers semaglutide, tirzepatide, BPC-157, CJC-1295, "and many other research peptides")
- USP-monograph compliance testing
- Hemp / cannabis
- Corn and grain analytics
- Synthetic food colors
- Pesticide residue screening
- Batch release
- BPA / BPS
- FDA import-detention analysis

## Pricing

| Assay | Price | Turnaround | Confidence |
|---|---|---|---|
| Any retail line | — | — | **Not published.** Quote-based engagements via contact form. |
| Finnrick-routed samples | User-facing cost = Finnrick's free / paid tier | ~1–3 weeks via Finnrick | C3 — Finnrick does not break out per-partner cost |

## Submission workflow

1. Contact via krauselabs.com/contact (no self-serve portal).
2. Quote-based engagement; not a walk-in consumer lab.
3. For individual testing: most community samplers are routed via Finnrick rather than direct.

## Sample requirements

- Lyophilized peptide: standard vial
- Oil / small-molecule: per-contract protocol
- Form factors accepted: broad (peptide, oil, powder, supplement, food matrix, raw chemistry)
- Anonymity: **no** — contract engagement requires identified client

## Publication practice

- **Methodology PDF:** `https://www.finnrick.com/labs-contents/peptide_reproducibility_questionnaire_krause.pdf` — Krause's answers to Finnrick's 10-question peptide-reproducibility methodology questionnaire. The PDF is a **scanned image** (not text-searchable); round-1 WebFetch returned binary corruption and round-2 has not OCR'd it. The fact that methodology answers exist is documented; the content is not accessible in this corpus. (Critique acknowledges this as an unknown — see `research/summary.md` C5 list.)
- **COAs:** issued per-client; not publicly aggregated by Krause themselves. Finnrick publishes the MZ/Krause COAs as part of per-product reporting.
- **Peer-reviewed publications:** none surfaced under "Krause Analytical" or "Mark Krause Austin analytical chemistry" on a quick search, 2026-04-23.

## Reputation notes (public statements only — no speculation)

- The site references **ISO 17025** alongside City-of-Austin, USEPA, and FDA FEI registrations in the footer, but does not display an accreditation number or scope. Treat ISO 17025 as C3 — mentioned but not documented to the level a QA auditor would want. (Critique did not flag this specifically; round-2 observation.)
- Finnrick's dominant partner by volume. This is an ecosystem fact, not a quality claim — high-volume partners get to be high-volume because they say yes to throughput, which doesn't itself signal quality relative to more bespoke partners like MZ Biolabs.
- No controversies or corrections circulating in community-review writeups as of 2026-04-22.
